This book is intended as a textbook for students and investigators interested in the physical aspect of ferromagnetism. The level of presentation assumes only a basic knowledge of electromagnetic theory and atomic physics and a general familiarity with rather elementary mathematics. Throughout the book the emphasis is primarily on explanation of physical concepts rather than on rigorous theoretical treatments which require a background in quantum mechanics and high-level mathematics.
Ferromagnetism signifies in its wide sense the strong magnetism of attracting pieces of iron and has long been used for motors, generators, transformers, permanent magnets, magnetic tapes and disks. On the other hand, the physics of ferromagnetism is deeply conceed with quantum-mechanical aspects of materials, such as the exchange interaction and band structure of metals. Between these extreme limits, there is an intermediate field treating magnetic anisotropy, magnetostriction, domain structures and technical magnetization. In addition, in order to understand the magnetic behavior of magnetic materials, we need some knowledge of chemistry and crystallography.
The purpose of this book is to give a general view of these magnetic phenomena, focusing its main interest at the center of this broad field. The book is divided into eight parts. After an introductory description of magnetic phenomena and magnetic measurements in Part I, the magnetism of atoms including nuclear magnetism and microscopic experiments on magnetism, such as neutron diffraction and nuclear magnetic resonance (NMR), is treated in Part II. The origin and mechanism of para-, ferro- and ferrimagnetism are treated in Part III. Part IV is devoted to more material-oriented aspects of magnetism, such as magnetism of metals, oxides, compounds and amorphous materials. In Part V, we discuss magnetic anisotropy and magnetostriction, to which I have devoted most of my research life. Part VI describes domain structures, their observation technique and domain theory. Part VII is on magnetization processes, analyzed on the basis of domain theory. Part VIII is devoted to phenomena associated with magnetization such as magnetothermal, magnetoelectrical and magneto-optical effects, and to engineering applications of magnetism.
Throughout the book, the SI or MKSA system of units using the E-H analogy is used. As is well known, this system is very convenient for describing all electromagnetic phenomena without introducing troublesome coefficients. This system also uses practical units of electricity such as amperes, volts, ohms, coulombs and farads. This system is particularly convenient when we treat phenomena such as eddy currents and electromagnetic induction which relate magnetism to electricity. However, old-timers who are familiar with the old CGS magnetic units such as gauss, oersted, etc. , must change their thinking from these old units to new units such as tesla, ampere permeter, etc. Once they become familiar with the new magnetic unit system, however, they may come to appreciate its convenience. To aid in the transition, a conversion table between MKSA and CGS units is given in Appendix 5.
In the previous edition I tried to refer to as many papers as possible. By the time of the revised edition, so many papers had become available that I was obliged to select only a small number of them to keep the text clear and simple. I have no doubt omitted many important papers for this reason, for which I apologize and beg their authors for tolerance and forgiveness. Many authors have kindly permitted me to use their beautiful photographs and unpublished data, for which I want to express my sincere thanks.
This book was originally published in Japanese by Shyokabo Publishing Company in Tokyo in 1959. The English version of that edition was published by John Wiley & Sons, Inc. in New York in 1964. The content of the English version was increased by about 55% from the Japanese version. At that time my English was polished by Dr Stanley H. Charap. A revised Japanese edition was published in two volumes in 1978 and 1984, respectively. The content was about 30% larger than the previous English edition. The preparation of the present English version of the revised edition was started in 1985 and took about ten years. This time my English was polished by Professor C. D. Graham, Jr using e-mail communication. The content has not been greatly increased, but has been renewed by introducing recent developments and omitting some old and less useful material.
