Description
Book SynopsisThis book is an application of quantum and statistical mechanics to the field of magnetism. The microscopic theory of many electron systems is presented in detail. Emphasis is given on how to solve the equations numerically with the use of computer programmes and how to apply them to problems arising in mechanical engineering or material sciences.
Trade ReviewTheory of Itinerant Electron Magnetism by Jurgen Kubler 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). The author concentrates on itinerant electron systems and emphasizes the importance of the electronic structure to the understanding of magnetic properties of realistic materials. Furthermore, Kubler cautions the reader that LDA does not correspond to the independent-particle picture; he advocates the extensive use of computers to solve the many-electron problem within LDA. However, he makes it very clear that LDA programs running on even the most efficient computers are not the answer to all magnetism questions, particularly those dealing with strongly correlated electron systems, for which no controlled general theory truly exists[...] This book will be useful to many researchers, theorists, and experimentalists alike. * Physics Today *
