E-Book Overview
The Handbook of Magnetic Materials has a dual purpose; as a textbook, it provides an introduction to a given topic within magnetism, and as a work of reference, it serves scientists active in magnetism research. To fulfill these two goals, each chapter in the Handbook is written by leading authorities in the field, and combines state-of-the-art research results with an extensive compilation of archival knowledge. Magnetism is a rapidly expanding field which constantly continues to encompass new phenomena. Examples of such subfields of magnetism are quadrupolar interactions, magnetic superconductors, and quasiscrystals: topics that are all covered in the present volume. The only common ground between these new materials and ferromagnets, is the possession of a magnetic moment; the series title has been slightly adjusted to reflect this. But in keeping with tradition, the Handbook of Magnetic Materials continues to allow readers to acquaint themselves in great depth with topics through the entire breadth of magnetism research.

PREFACE This H a n d b o o k on the Properties of Magnetically Ordered Substances, Ferromagnetic Materials, is intended as a comprehensive work of reference and textbook at the same time. As such it aims to encompass the achievements both of earlier compilations of tables and of earlier monographs. In fact, one aim of those who have helped to prepare this work has been to produce a worthy successor to Bozorth's classical and monumental book on Ferromagnetism, published some 30 years ago. This older book contained a mass of information, some of which is still valuable and which has been used very widely as a work of reference. It also contained in its text a remarkably broad coverage of the scientific and technological background. One man can no longer prepare a work of this nature and the only possibility was to produce several edited volumes containing review articles. The authors of these articles were intended to be those who are still active in research and development and sufficiently devoted to their calling and to their fellow scientists and technologists to be prepared to engage in the heavy tasks facing them. The reader and user of the H a n d b o o k will have to judge as to the success of the choice made. Each author had before him the task of producing a description of material properties in graphical and tabular form in a broad background of discussion of the physics, chemistry, metallurgy, structure and, to a lesser extent, engineering aspects of these properties. In this way, it was hoped to produce the required combined comprehensive work of reference and textbook. The success of the work will be judged perhaps more on the former than on the latter aspect. Ferromagnetic materials are used in remarkably many technological fields, but those engaged on research and development in this fascinating subject often feel themselves as if in strife for superiority against an opposition based on other physical phenomena such as semiconductivity. Let the present H a n d b o o k be a suitable and effective weapon in this strife! The publication of Volumes 1 and 2 took place in 1980 and produced entirely satisfactory results. Many of the articles have already been widely quoted in the scientific literature as giving authoritative accounts of the modern status of the

The present Volume 3 goes halfway towards this event and contains articles on a variety of subjects. There is a certain degree o f coherence in the topics treated her
