The book begins with a personal tribute to Warren E. Henry and a reprint of one of his influential papers from "Physical" "Review." The following proceedings give a comprehensive view of recent research on the topic of magnetism, including topics from theoretical and experimental perspectives. Contributions include papers on the theoretical relationship between magnetic phenomena and superconductivity, a new class of magnetic materials produced by molecular beam epitaxy, non-linear phenomena in magnetization fields, quantum chaos in magnetic phenomena, and magnetic devices and anisotropy. The volume brings together original papers written by experts in various areas of the field of magnetism. This is one of the first books in recent years to treat all facets of the field of magnetics. The book will be a useful survey for researchers, engineers and graduate students.
