"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."--BOOK JACKET.

A very comprehensive book, enabling the reader to understand the basic formalisms used in electronic structure determination and particularly the "Muffin Tin Orbitals" methods. The latest developments are presented, providing a very detailed description of the "Full Potential" schemes. This book will provide a real state of the art, since almost all of the contributions on formalism have not been, and will not be, published elsewhere. This book will become a standard reference volume. Moreover, applications in very active fields of today's research on magnetism are presented. A wide spectrum of such questions is covered by this book. For instance, the paper on interlayer exchange coupling should become a "classic", since there has been fantastic experimental activity for 10 years and this can be considered to be the "final" theoretical answer to this question. This work has never been presented in such a complete form.

The Electronic Structures of Solids aims to provide students of solid state physics with the essential concepts they will need in considering properties of solids that depend on their electronic structures and idea of the electronic character of particular materials and groups of materials. The book first discusses the electronic structure of atoms, including hydrogen atom and many-electron atom. The text also underscores bonding between atoms and electrons in metals. Discussions focus on bonding energies and structures in the solid elements, eigenstates of free-electron gas, and electrical conductivity. The manuscript reviews the presence of electrons in metals, as well as consequences of the periodic potential; Brillouin zones and the nearly-free-electron model; electronic structures of the metallic elements; and calculation of band structures. The text also ponders on metals, insulators, and semiconductors. Topics include full and empty bands, compound and doped semiconductors, optical properties of solids, and the dynamics of electron and holes. The book is a dependable reference for readers and students of solid state physics interested in the electronic structure of solids.

The aim of this book is to review recent achievements in thetheoretical 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 presentsthe theoretical foundations of the band theory of solids such as thedensity functional theory for ground state properties of solidsincluding local density approximation (LDA). It also presents somemodifications to the LDA, such as gradient correction, self-interaction correction, LDA+U method, orbital polarizationcorrection, GW approximation, and dynamical mean- field theory. Thedescription of the magneto-optical effects and linear response theoryare also presented.The book describes the MO properties for a number of 3d materials, such as elemental ferromagnetic metals (Fe, Co and Ni) andparamagnetic metals in external magnetic fields (Pd and Pt), someimportant 3d compounds such as XPt3 (X=V, Cr, Mn, Fe and Co), Heusleralloys, chromium spinel chalcogenides, MnB and strongly correlatedmagnetite Fe304. It also describes the recent achievements in both theexperimental and theoretical investigations of the electronicstructure, optical and MO properties of transition metal multilayeredstructures (MLS).The book presents also the MO properties of f band ferromagneticmaterials: Tm, Nd, Sm, Ce and La monochalcogenides, some important Y

This dissertation describes first-principles quantum mechanical investigations of several realistic solid-state systems. The main goal of this research has been to understand and predict the electronic, vibrational, and structural properties of materials under pressure. Microscopic information on these properties is obtained within local density functional theory using ab initio pseudopotentials. This work focuses on three categories of materials: (1) Part I deals with the high-pressure behavior of elemental systems from group IV of the Periodic Table. The pressure-dependences of Raman-active phonon modes of high-pressure, metallic phases of silicon, germanium, and tin are studied within the frozen-phonon approximation. In addition, the structural properties of a recently discovered orthorhombic phase of silicon are calculated. The aim of these two investigations is to understand and explain recent experimental results. A third investigation predicts the existence of an orthorhombic, high-pressure phase of germanium. (2) Part II focuses on group V of the Periodic Table. The electronic and vibrational properties of elemental arsenic are studied with the aim of understanding the measured pressure-dependences of the superconducting transition temperature and the normal-state resistance. In addition, several candidate atomic phases of solid nitrogen are studied to determine their structural-stability and electronic properties. (3) Finally, Part III considers the effect of varying the stoichiometry in compound systems. In particular, model calculations are performed to explore the Ga-As system with the goal of motivating experimental studies. The electronic properties of several model Ga-As systems with varying stoichiometry are studied.

This volume on the novelties in the electronic properties of solids appears in occasion of Franco Bassani sixtieth birthday, and is dedicated to honour a scientific activity which has contributed so much of the development of this very active area of research. It is re markable that this book can cover so large a part of the current research on electronic properties of solids by contributions from Bassani's former students, collaborators at different stages of his scientific life, and physicists from all over the world who have been in close scientific relationship with him. A personal flavour therefore accompanies a number of the papers of this volume, which are both up-to-date reports on present research and original recollections of the early events of modern solid state physics. The volume begins with a few contributions dealing with theoretical procedures for electronic energy levels, a primary step toward the interpretation of structural and optical properties of extended and confined systems. Other papers concern the interacting state of electrons with light (polaritons) and the effect of the coupling of electrons with lattice vibrations, with emphasis on the thermal behaviour of the electron levels and on such experimental procedures as piezospectroscopy. Electron-lattice interaction in external magnetic field and transport-related properties due to high light excitation are also con sidered. The impact of synchroton radiation on condensed matter spectroscopy is dis cussed in a topical contribution, and optical measurements are presented for extended and impurity levels.
