The aim of this book is to review recent achievements in the
theoretical investigations of the electronic structure, optical,
magneto-optical (MO), and x-ray magnetic circular dichroism (XMCD)
properties of compounds and Multilayered structures.
Chapter 1 of this book is of an introductory character and presents
the theoretical foundations of the band theory of solids such as
the density functional theory for ground state properties of solids
including local density approximation (LDA). It also presents some
modifications to the LDA, such as gradient correction,
self-interaction correction, LDA+U method, orbital polarization
correction, GW approximation, and dynamical mean-field theory. The
description of the magneto-optical effects and linear response
theory are also presented.
The book describes the MO properties for a number of 3d materials,
such as elemental ferromagnetic metals (Fe, Co and Ni) and
paramagnetic metals in external magnetic fields (Pd and Pt), some
important 3d compounds such as XPt3 (X=V, Cr, Mn, Fe and Co),
Heusler alloys, chromium spinel chalcogenides, MnB and strongly
correlated magnetite Fe304. It also describes the recent
achievements in both the experimental and theoretical
investigations of the electronic structure, optical and MO
properties of transition metal multilayered structures (MLS).
The book also presents the MO properties of f band ferromagnetic
materials: Tm, Nd, Sm, Ce and La monochalcogenides, some important
Yb compounds, SmB6 and Nd3S4, UFe2, U3X4 (X=P, As, Sb, Bi, Se and
Te), UCu2P2, UCuP2, UCuAs2, UAsSe, URhA1, UGa2 and UPd3. Within the
total group of alloys and compounds, we discuss their MO spectra in
relationship to: the spin-orbit coupling strength, the magnitude of
the local magnetic moment, the degree of hybridization in the
bonding, the half-metallic character, or, equivalently, the Fermi
level filling of the bandstructure, the intraband plasma frequency,
and the influence of the crystal structure.
In the last chapter results of recent theoretical investigations on
the MXCD in various representative transition metal 4f and 5f
systems are presented.
