【Abstract】 Nanocrystalline composite permanent magnetic alloys has been paid great attention to in theresearch field of permanent magntic materials in recent years. It has a different magnetic hard-ning mechanism from other isotropic rare-earth permanent magnets and unified high magneticproperties. Development process of this type of permanent magnetic alloys is described and re-search status on theory and experiment is reviewed in this paper.更多还原
