Opis

Recent developments in electronic structure theory have led to a new understanding of magnetic materials at the microscopic level. This enables a truly first-principles approach to investigations of technologically important magnetic materials. Among the advances treated here have been practical schemes for handling non-collinear magnetic systems, including relativity, and an understanding of the origins and role of orbital magnetism within band structure formalisms. This book provides deep theoretical insight into magnetism, mahneatic materials, and magnetic systems. It covers these recent developments with review articles by some of the main originators of these developments.

Recenzje

From the reviews:

"This book reports the successes and the failures of the various theories devised to explain and/or predict the properties of complex magnetic materials. ... The present book stresses the interplay between theory and experiment and provides several excellent illustrations of the scientific method. ... This book, which is very interesting in the way it emphasizes the interplay between theory and experiment, is aimed at physicists and materials scientists, both theoreticians and experimentalists, carrying research on magnetic materials." (Fernande Grandjean and Gary J. Long, Physicalia, Vol. 26 (1), 2004)

"The authors of the various chapters have done well in linking density functional theory with experiment in magnetic systems, highlighting both successes and failures and providing comprehensive references in support of their discussions. ... I have gained a greater appreciation of interplay between electronic and local forces in determination of magnetic order and I would recommend this book to researchers with strong interest in this area." (S S J Kennedy, The Physicist, Vol. 40 (5), 2003)

Recent developments in electronic structure theory have led to a new understanding of magnetic materials at the microscopic level. This enables a truly first-principles approach to investigations of technologically important magnetic materials. Among these advances have been practical schemes for handling non-collinear magnetic systems, including relativity, understanding of the origins and role of orbital magnetism within band structure formalisms, density functional approaches for magnons and low-lying spin excitations, understanding of the interplay of orbital, spin and lattice orderings in complex oxides, transport theories for layered systems, and the theory of magnetic interactions in doped semiconductors. The book covers these recent developments with review articles by some of the main originators of these advances.
