For upper-level undergraduate students, and first-year graduate students in materials science, metallurgy, electrical engineering, and applied physics.;This Third Edition is the result of a thorough re-examination of the entire text, incorporating suggestions and corrections by students and professors who have used the text. Explanations and descriptions have been expanded, and additional information has beeen added on high Tc, superconductors, diamond films, "buckminsterfullerene", and thin magnetic materials. Adopted by more than 20 colleges and universities, this text has proven to be a solid introduction to the electrical, optical, and magnetic properties of materials.;It contains comprehensive coverage of electronic properties in metals, semiconductors, and insulators at a fundamental level; stresses the use of wave properties as an integrating theme for the discussion of phonons, photons, and electrons; includes a complete set of illustrative problems along with exercises and answers; and features a careful indication of both Gaussian and SI unit systems.
"High-Tc Superconductivity" is based on a meeting held in Kiev and contains contributions discussing the most recent achievements in this field. The book includes reviews and original papers covering theoretical and experimental aspects of the subject. Keywords: electronic and magnetic properties, metallization processes, emission and optic spectra, lavitation, pinning, frustration and fluctuations, thin films
This booklet presents a study of one-dimensional waves in solids which can be modelled by nonlinear wave equations of different types. The factorization method is the main tool in this analysis. It allows for an exact or at least asymp totic decomposition of the wave(s) under consideration in terms of first order multipliers. Chapter 1 provides a general introduction. It presents some well-known results on characteristics, Riemann invariants, simple waves, etc. The main result of Chap. 1 is Theorem 1.3.2. (Sect. 1.3.2) which establishes the possibility of exact factorization of the nonlinear wave equation EPa(a) 1 EPa _ 0 Ij(l-u- x2 with constant coefficients. This theorem permits one to construct further factor izations of more complicated wave equations which the reader will meet in the following chapters. Chapter 2 is devoted to short wave processes in inhomogeneous media, the main result being the uniform asymptotic factorization of nonlinear wave equa tions with variable coefficients and the description of corresponding single-wave processes without the usual assumption of a small wave amplitude."
Advances in the physics and chemistry of low-dimensional systems have been really magnificent in the last few decades. Hundreds of quasi-one-dimensional and quasi-two-dimensional systems have been synthesized and studied. The most popular representatives of quasi-one-dimensional materials are polyacethylenes CH 1] and conducting donor-acceptor molecular crystals TIF z TCNQ. Examples of quasi-two-dimensional systems are high temperature su perconductors (HTSC) based on copper oxides LA2CU04, YBa2Cu306+y and organic superconductors based on BEDT -TIP molecules. The properties of such one- and two-dimensional materials are not yet fully understood. On the one hand, the equations of motion of one-dimensional sys tems are rather simple, which facilitates rigorous solutions of model problems. On the other hand, manifestations of various interactions in one-dimensional systems are rather peculiar. This refers, in particular, to electron--electron and electron-phonon interactions. Even within the limit of a weak coupling con stant electron--electron correlations produce an energy gap in the spectrum of one-dimensional metals implying a Mott transition from metal to semiconductor state. In all these cases perturbation theory is inapplicable. Which is one of the main difficulties on the way towards a comprehensive theory of quasi-one-dimensional systems. - This meeting held at the Institute for Theoretical Physics in Kiev May 15-18 1990 was devoted to related problems. The papers selected for this volume are grouped into three sections."
'The text provides an interesting history of previous and anticipated accomplishments, ending with a chapter on the relationship of fusion power to nuclear weaponry. They conclude on an optimistic note, well worth being understood by the general public.'CHOICEThe gap between the state of fusion energy research and public understanding is vast. In an entertaining and engaging narrative, this popular science book gives readers the basic tools to understand how fusion works, its potential, and contemporary research problems.Written by two young researchers in the field, The Future of Fusion Energy explains how physical laws and the Earth's energy resources motivate the current fusion program — a program that is approaching a critical point. The world's largest science project and biggest ever fusion reactor, ITER, is nearing completion. Its success could trigger a worldwide race to build a power plant, but failure could delay fusion by decades. To these ends, this book details how ITER's results could be used to design an economically competitive power plant as well as some of the many alternative fusion concepts.
During the last decades the knowledge of the magnetic properties of the d transition elements and of their metallic alloys and compounds has increased widely. The improvement of preparation techniques for well-defined substances, the development of sophisticated measuring methods and above all the drive to obtain more insight in the origin of magnetic interactions in solids have resulted in the publication of many specific magnetic properties for an abundance of all kinds of metallic materials. The data assembled in this booklet are selected from the comprehensive compilation of magnetic and related properties of metals in the Landolt-Bornstein New Series Group III sub volumes 19a, band c. It has been attempted to include preferentially those properties which are of a basic character and which therefore are most often needed by scientists active in the field of solid state magnetism. In the field of magnetism, there is a gradual transition from the use of cgs/emu units to SI units. It was, however, not intended to represent all data in the units of one system, regardless of how nice this would have been from a systematic point of view. Instead, mostly preference was given to the system of units that was originally used by the authors whose work is quoted. Thus cgs/ emu units occur most frequently. Of colirse the user of the tables and figures is helped in several ways to convert the data to the units which he is most familiar with, see, e. g."
This short biography aims to show, in non-technical language, how one major scientist lived and worked. It marks the bicentenary of Faraday's birth.
This book is about pulse nuclear magnetic resonance (NMR), with its techniques, the information to be obtained, and practical advice on performing experiments. The emphasis is on the motivation and physical ideas underlying NMR experiments and the actual techniques, including the hardware used. The level is generally suitable for those to whom pulse NMR is a new technique, be they students in chemistry or physics on the one hand and research workers in biology, geology, or agriculture, on the other. The book can be used for a senior or first year graduate course where it could supplement the standard NMR texts.
This volume contains the lectures of "Earlier and Recent Aspects of Super conductivity," the 18th course of the International School of Materials Science and Technology, which was held at the Ettore Majorana Centre for Scientific Culture in Erice (Sicily), Italy, July 4-16, 1989. In the wake of the discovery of high-Tc oxides many international confer ences have been held on the subject, mainly intended for those already working in high-Tc research. Hence, the idea evolved of organizing a school dedicated to students and young scientists entering the field of superconductivity. The intention was to give a broad perspective of the field with its eight decades of research history and thus to link existing fields of knowledge and gain con tinuity. The new high-Tc cuprates were integrated, both historically and by subject, into the field of classical superconductivity, as well as into its newer branches of heavy-fermion, organic and chalcogenide superconductors. Even the organizers and the lecturers were surprised how many cross-links became apparent between the different branches of superconductivity. The lectures have been grouped into four parts, namely: - Fundamental properties of superconductors - Coherence-length-related properties - Electronic and magnetic properties - Theoretical models The number of applications from potential participants greatly exceeded the capacity of the facilities available. Ultimately, 100 students from 25 coun tries were selected to attend the course. The remarkable surroundings of the medieval town of Erice promoted a most stimulating but nevertheless relaxed atmosphere."
This volume contains extended abstracts of the 10 plenary lectures, 27 invited symposium lectures and ap- proximately 300 contributed papers that were presented at the 25th Congress Ampere. The contributions cover the full range of magnetic resonance and radiospectroscopy and their applications in physics, chemical physics, medicine and biology. Advanced NMR and ESR techniques are treated, as are their applications to novel materials.
Die mobile Funkkommunikation ist einer der Wachstumsmarkte unserer Zeit. Fur die Planung zellularer Mobilfunknetze werden dabei verlasstliche Werkzeuge benoetigt, deren Benutzung und Weiterentwicklung nur bei Kenntnis aller Grundlagen und der verwendeten Loesungsverfahren erfolgreich sein kann. Der vorliegende Text versucht, diese grundlegenden Kenntnisse fur einige der wesentlichen Teilaufgaben in der Funknetzplanung zu vermitteln. In der Vielzahl ausgezeichneter Bucher zu den primar nachrichtentechnischen Aspekten des Mobilfunks wird der Beschreibung und Analyse des Funkkanals zwischen den Antennentoren ein vergleichsweise geringer Rahmen beigemessen. Ziel des vorliegenden Buches ist es, diese Lucke zu fullen. Da sich die Charakterisierung des Funkkanals fur verschiedene Funksysteme nicht oder nur wenig unterscheidet, lassen sich die meisten der eroerterten Grundlagen und Verfahren auch auf andere Funksysteme, wie z.B. Rundfunk oder Richtfunk, anwenden.
Reprint from Pure and Applied Geophysics (PAGEOPH), Volume 131 (1989), No. 3
Starting with a historical introduction to the study of magnetism - one of the oldest sciences known to man - before considering the most modern theories and observations (magnetic bubbles and soap films, effects of magnetic impurities in metals and spin glasses), this book develops the concepts and the mathematical expertise necessary to understand contemporary research in this field. Magnetic systems are important in technology and applied science, but they are also prototypes of more complex mathematical structures of great importance to theoretical physics. These connections are made repeatedly in this volume. After development of the necessary quantum theory of angular momentum and of interacting electron systems, a number of models which have been successful in the interpretation of experimental results are introduced: the Ising model, the Heisenberg model, the Stoner theory, the Kondo phenomenon, and so on. In the second edition the thorough approach and the main features which made the first edition a popular text have been retained. All important theories are worked out in detail using methods and notation that are uniform throughout. Footnotes and an extensive bibliography provide a guide to the original literature. A number of problems test the reader's skill.
I have tried in this book to introduce the basic concepts of electromagnetic field theory at a level suitable for students entering degree or higher diploma courses in electronics or subjects allied to it. Examples and applications have been drawn from areas such as instrumentation rather than machinery, as this was felt to be more apt for the majority of such readers. Some students may have been following courses with a strong bias towards prac tical electronics and perhaps not advanced their understanding of the physics of electric and magnetic fields greatly since '0' level or its equivalent. The book there fore does not assume that 'A' level physics has been studied. Students of BTEC courses or 'A' level subjects such as technology might also find the material useful. At the other extreme, students who have achieved well on an 'A' level course will, it is hoped, find stimulating material in the applications discussed and in the marginal notes, which suggest further reading or comment on the deeper implica tions of the work."
This is the first ever compendium of double photoionisation spectra, covering some 70 of the most important small and medium sized molecules and thus providing an essential starting point for studies of the consequences of ionisation by high energy photons in both terrestrial and astrophysical environments. It also provides a complete non-mathematical description of all the phenomena and pathways involved in molecular double photoionisation. Most spectra are presented with identification of the electronic states and leading orbital configurations. The technique of magnetic bottle time-of-flight electron spectroscopy, used for all the spectra, is fully explained and compared with other techniques. For each molecule, the book gives full references to relevant work by complementary techniques and to theoretical calculations. Written in a clear non-mathematical style, this book is accessible to students as well as more experienced researchers. The authors have designed the layout for easy retrieval of any desired spectrum through the systematic organisation and ordering of the compounds and thorough indexing. As well as being a compendium of spectra, the book is a textbook covering all the known phenomenological aspects of molecular double photoionisation. The important phenomena are first mentioned in the introductory chapters, and are discussed in more detail in connection with the groups of molecules and individual cases where they are most relevant. The most useful spectra will be available in digital form for users.
Electromagnetism is basic to our understanding of the properties of matter and yet is often regarded as a difficult part of an under graduate physics course. In this book answers are developed from first principles to such questions as: What is electricity? What is electromagnetism? Why are some materials magnetic and others non-magnetic? What is magnetism? Physics answers these questions in two related ways. On the one hand the classical explanation is in terms of classical concepts: electric charge q, electric and magnetic fields (E and B) and electric currents. On the other hand the microscopic (or 'atomic ') explanation is in terms of quantum concepts: electrons, nuclei, electron orbits in atoms, electron spin and photons. Microscopic explanations underlie classical ones, but do not deny them. The great triumphs of classical physics are mechanics, gravitation, thermodynamics, electromagnetism and relativity. Historically they began at the time of Newton (seventeenth century) and were completed by Maxwell (nineteenth century) and Einstein (early twentieth century). Microscopic explanations began with J J. Thomson's discovery of the electron in 1897. For most physical phenomena it is best to seek a classical explanation first, especially phenomena at room temperature, or low energy, when quantum effects are small. Although this text is primarily concerned with classical explanations in a logical, self-consistent sequence, they are related to microscopic (quantum) explanations at each stage."
This is the first book devoted to the use of X-ray beam techniques to study magnetic properties of materials. It covers both experimental and theoretical issues. The three main topics are dichroism, elastic scattering (both non-resonant and resonant diffraction) and spectroscopy. In the past decade there has been an expansion of activity in the field, driven by the availability of intense, tuneable and highly polarized X-ray beams from synchrtron facilities. The pace of events is likely to continue with the start of new (3rd generation) facilities, including the European Synchrotron Radiation Facility, Grenoble, and the Advanced Light Source, Argonne National Laboratory. USA.
Resonances are a common feature of many systems in nature. They reveal much about the structure of such systems. This book provides a comprehensive and up-to-date account of a similar phenomenon in atomic nuclei, the giant resonances. It describes experimental facts, how these are obtained, and how they fit into existing theoretical models. It also includes a short history and an overview of the main achievements in this field.
The popularity of the First Edition of this book has been very gratifying. It confirms that there is a genuine need for a text covering the magnetic bubble technology. We are pleased that the readers have found that this book satisfies that need. It has been used as a text for courses in both universities and industry, and as a reference manual by workers active in the field. To meet the need for more copies of the book it seemed preferable to publish a second edition rather than merely a second printing. There has been some significant progress, even in the short time since the initial printing, and we wanted to include that. At the same time we would like to provide the new copies at the lowest possible cost so that they are more easily obtained by students. For this reason the new edition is in soft cover and the recent progress has been described in a final chapter rather than incorporated into the original chapters. This eliminates the expense of resetting and repaging the original text. At the same time up-to-date references have been added and typographical errors have been corrected in the original chapters. It is our hope that this edition will be useful to those with an interest in the fascinating field of magnetic bubbles.

The science of superconducting electronics was first developed over forty years ago, fifty years after the discovery of superconductivity. Since then, a wide range of applications has emerged, and more are envisaged within this ever expanding and exciting field. SQUIDs, the Josephson Effects and Superconducting Electronics chronicles this development from fundamental principles to the present work with high-temperature superconductors. The book discusses superconductivity, Josephson effects, and detectors of unparalleled sensitivity such as SQUIDs. It punctuates theory with practical discussions on how to harness this new science. This complete guide to the subject is an invaluable resource for graduate students and researchers with a specific interest in this field. It also provides guidance to those working in areas of industry where superconducting electronics could be applied.
This book attempts to trace the key experimental developments that led to the discovery of weak neutral currents in 1973 and the W, Z bosons in 1983, all of the results of which culminated in the identification of the unified-electroweak force. |
