Studies Involving the Synthesis and Characterization of High Energy Magnet Materials

Abstract

Permanent magnets are essential components of a wide range of modern devices, many of which have military significance - travelling wave tubes, klystrons, linear induction accelerators, high power free electron lasers, high performance motors and generators, etc. Higher energy permanent magnets enable one to downsize the various devices which operate via permanent magnets. The present study had as its main objectives: (a) improving existing high energy magnets and (b) developing new magnets. The systems studied with this in mind fall into three structural types: those having (a) the Nd2Fe14B structure, (b) the ThMn12 structure and (c) the Sm2Co17 structure. Results of the studies are presented in 26 papers published in the open literature. Highlights of the work are provided in this report by giving terse summaries of 9 of the papers. The work has been a part of the world-wide effort to make Nd2Fe14B magnets into a commercial reality.
