PrFeB纳米晶磁体的颗粒分布对其矫顽力的影响

摘要

Nanocrystalline permanent magnets (PM) have attracted great interest because of their low rareearth content and relatively high maximum energy production. Many efforts have been made to understand the effects of grain size on coercivity and remanence. Due to the limit of experimental technology, the effects of grain distribution on the magnetic properties in PM were scarely investigated.
