The aim of this book is to provide both an introduction and a state-of-the-art report on research into magnetism and magnetic materials. Particular emphasis has been put on the contribution of synchrotron radiation in relevant experimental investigations. Graduate students and nonspecialists will benefit from the tutorial approach while specialists will find the latest results that round off the material presented in the lectures.The aim of this book is to provide both an introduction and a state-of-the-art report on research into magnetism and magnetic materials.
