This book provides an up-to-date review of nanometer-scale magnetism and focuses on the investigation of the basic properties of magnetic nanostructures. It describes a wide range of physical aspects together with theoretical and experimental methods. A broad overview of the latest developments in this emerging and fascinating field of nanostructured materials is given with emphasis on the practical understanding and operation of submicron devices based on nanostructured magnetic materials.

Interest in research on nanoscale materials is steadily increasing: nano-structured magnetic materials exhibit new and interesting physical properties, which cannot be found in the bulk. Many of these unique properties have great potential for technical applications in magneto-sensors, bio-sensors, magneto-electronics, data storage, magnetic heads of computer hard disks, single-electron devises, microwave electronic devices, etc. Current research concentrates on device design, synthesis and the characterization of nanostructured materials. The contributions to this book concentrate on magnetic properties of nanoscale magnetic materials, especially on fabrication and characterization, and the physics underlying the unique properties of these structures and devices.

This book focuses on the investigation of the basic properties of magnetic nanostructures, and the fundamental physics of novel nanostructures for submicron devices. It provides a broad overview of the latest developments in this emerging and fascinating field of nano-sized materials, with emphasis on the practical understanding and operation of devices using or based on nanostructured magnetic materials. The topics also include submicron technologies, nanoscale characterization, new techniques for the synthesis of nanoparticles as well as an in-depth treatment of their characterization and chemical and physical properties. Potential industrial applications of these advanced materials are also discussed.

This volume addresses the exciting and rapidly developing topic of ultrahigh-density magnetic data storage. It is the most advanced book on magnetic nanostructures, basics and applications. It combines modern topics in nanomagnetism with issues relating to the fabrication and characterization of magnetic nanostructures. This book will be of interest to R and D scientists and it provides an accessible introduction to the essential issues.
