摘　　要：稀土永磁材料是以稀土金属元素与过渡族金属所形成的金属间化合物为基本的永磁材料 ,稀土永磁材料的磁性能与组成该永磁体的稀土化合物的晶体结构有密切关系 .了解稀土永磁化合物的结构将为了解稀土永磁材料的性能和制造工艺打下基础 .本文介绍了目前取得较大进展的新型稀土永磁材料的研究成果 .Rare-earth permanent magnet materials are mostly formed with intermetallic compounds which are synthesized by rare-earth element and transition metals.The magnetic property of rare-earth permanent magnet materials has close relation with the crystal structures of rare-earth compounds.Finding out the structure and the conversion of rare-earth permanent magnet materials will build solid foundation of its properties manufacture technique.This paper presents the result of the research of novel rare-earth permanent-magnetic materials being achieved at present.
