Considers permanent magnetism based on the new materials of ceramics and intermetallic compounds, currently the subject of much research and widespread industrial application in electromagnetic applications and for magnetic storage of data
Presents complex ideas with clarity and insight
Requires graduate-level knowledge of physics and materials science
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.
