摘要
Sm Fe N的出现 ,再次促使对Sm Fe系进行广泛而深入的研究 ,发现了SmFe7亚稳相的存在。基于其优异的内禀磁性 ,此相有可能作为新型高能积磁体的基材。为引起我国磁体产业界对SmFe7的足够重视 ,特对有关文献作一综述。
The Sm Fe system has attracted considerable attntion due to the appearance of Sm Fe N.The existence of a new metastable phase with chemical formula of SmFe 7 has been found during the recent study on Sm Fe system.Such phase can be served as the base for new generation of magnets.In order to cause the enou gh attention from Chinese magnet industry a summary on such material is given in present paper.
