Synopses & Reviews
This book, in the broadest sense, is an application of quantum mechanics and statistical mechanics to the field of magnetism. Under certain well described circumstances, an immensely large number of electrons moving in the solid state of matter will collectively produce permanent magnetism. Permanent magnets are of fundamental interest and magnetic materials are also of great practical importance as they provide a large field of technological applications. The physical details describing the many electron problem of magnetism are presented in this book on the basis of the local density functional approximation. The emphasis is on realistic magnets, for which the equations describing the many electron problem can only be solved by using computers. The great, recent and continuing improvements of computers are, to a large extent, responsible for the progress in the field. Along with a detailed introduction to the density functional theory, this book presents representative computational method and proves the reader with a complete computer program for the determination of the electronic structure of a magnet on a PC.
A large part of the book is devoted to a detailed treatment of the connections between electronic properties and magnetism, and how the differ in the various known magnetic systems. Current trends are exposed and explained for a large class of alloys and compounds. The modern field of artificially layered systems- knows as multilayers- and their industrial applications are dealt with in detail. Finally, an attempt is made to relate the rich thermodynamic properties of magnets to the ab inition results originating from the electronic structure.
Review
"[This work] is a unique contribution to the study of magnetism, in that it attempts to describe a substantial part of the field using the local density functional approximation (LDA). . . . Kübler does an excellent job of describing LDA and making connections between the electronic structure of several materials and their magnetic properties. . . . The book will be useful to many researchers, theorists, and experimentalists alike. . . . It offers a personal and focused view of itinerant magnetism based on LDA from a leading expert in the field, and it describes in detail the relationship between electronic structure and magnetic properties of itinerant electrons in realistic systems." -- Physics Today
