Rare-earth Iron Permanent Magnets

Rare-earth iron permanent magnets combine the magnetization of iron or cobalt with the anisotropy of a light rare-earth in intermetallic compounds which exhibit nearly ideal hysteresis. The rare-earth iron magnets are now indispensable components of a vast range of electronic and electromechanical devices. This book covers the principles of permanent magnetism, magnet processing, and applications in a series of interlocking chapters written by experts in each area. Born of experience of the Concerted European Action on Magnets, it is a definitive account of the field, designed to be read by physicists, materials scientists, and electrical engineers.

Magnets have been objects of fascination for millenia. The new rare-earth iron magnets store 1,000 times the energy of their predecessors, with applications ranging from personal stereos to computer drives to medical scanners. This book offers the first integrated account of the whole field, addressed to physicists, metallurgists and electrical engineers.
