Magnetism and magnetic materials 2nd Edition PDF

THE contents of this book started life as a course of eight lectures given to third year undergraduates reading Metallurgy and Science of Materials at Oxford. However, the book differs from the lecture course in two respects.

Firstly, I have tried to explain everything from first principles as far as possible, in the hope that readers new to the subject, including those with relatively little knowledge of mathematics, can benefit from it. Secondly, the fact that the course is limited to eight lectures imposes a restriction on the amount of material that can be covered, and therefore I have tried to include details for which there is no time in the lecture course.

This book is not intended to be a self-contained source of informationthere are many excellent texts that serve that purpose already. It should however enable readers to gain an understanding of a subject that may be new to them, or one they may have found difficult before, and it should encourage them to approach more advanced texts without feeling intimidated. For that reason I have included some advice on further reading in an appendix. At the same time, I hope that readers with some knowledge of magnetism (I trust my students can be included in that category) may find some useful information in the book.

Readers who explore the subject further will find not only many more details on the topics dealt with in this book, but entirely new areas that had to be excluded because this was meant to be a small volume. Examples of the latter are semihard materials, rare earth-transition metal compounds with giant magnetostriction, and ferromagnetic liquids. Information on these topics and many others will be found in the books recommended in the appendix.

It is a pleasure to thank present and former colleagues and other friends for supplying figures for the book. Fig. 3.21 was contributed by G. A. Jones, Fig. 3.23 by A. Hubert, Fig. 3.24 by A. Hubert and M. Riihrig, Fig. 3.28 by M. R. Scheinfein, Fig. 3.29 by 1. McFadyen and Fig. 3.30 by J. E. A. Miltat. Fig. 3.25 was taken by S. J. Newnham, Fig. 3.26 by D. C. Joy and Fig. 3.27 by D. J. Fathers. I am grateful to them all for their contributions. I am also grateful to S. M. Baker for assistance with obtaining Fig. 3.22 and the cover photograph, and to A. K. Petford-Long for reading parts of the manuscript. I also thank Oxford University Computing Service, and R. L. Hutchings in particular, for their help with typesetting this book.
