Informationen zum Autor J. M. D. Coey leads the Magnetism and Spin Electronics group at Trinity College, Dublin, where he is Erasmus Smith's Professor of Natural and Experimental Philosophy. An authority on magnetism and its applications, he has been awarded the Gold Medal of the Royal Irish Academy and the Charles Chree Medal of the Institute of Physics for his work on magnetic materials. Klappentext One of the first books to approach magnetism from a metal physics perspective, Permanent Magnetism presents research ideas that are being translated into commercial reality for ferrite and Nd-Fe-B magnets, and follows the discovery of interstitial, intermetallic materials. Written by well-known authors, the book contains a comprehensive yet concise treatment of the fundamental theory underlying permanent magnetism and illustrates applications with modern, permanent magnetic materials, including ceramics and intermetallic compounds. Each chapter contains worked examples to reinforce applications and the appendices include detailed mathematics and tabular data on material properties.
