Magnetic Properties of Fine Particles

by J.L. Dormann (Editor), D. Fiorani (Editor)

Overview

The aim of this volume is to advance the understanding of the fundamental properties of fine magnetic particles and to discuss the latest developments from both the theoretical and experimental viewpoints, with special emphasis being placed on the applications in different branches of science and technology.All aspects of fine magnetic particles are covered in the 46 papers. The topics are remarkably interdisciplinary covering theory, materials preparation, structural characterization, optical and electrical properties, magnetic properties studied by different techniques and applications. Some new fundamental properties, such as quantum tunneling and transverse fluctuations of magnetic moments are also explored. Research workers involved in these aspects of materials technology will find this book of great interest.
