摘要
3:29稀土金属间化合物具有单斜晶晶体结构,属于A2/m空间群组,是一种非常具有潜在应用价值的稀土永磁材料。文中介绍了几种不同的元素取代和间隙原子占位对磁性能的影响,描述了几种交换作用,总结了磁性机理,并对该永磁材料的研究作了评述。
As potential applicable permanent magnetic materials, 3 ： 29 type rare-earth intermetallic compounds belonging to A2/m spacial group have the monoelinic crystalline structure. The effect on magnetic performance through element substitute and occupation of interstitial atom are described. Several effects of exchange coupling and magnetic mechanism are introduced. Investigation of this magnetic materials are reviewed.
