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."
