永磁材料R_1-δ(2T)_δT₅型化合物(R=稀土元素,T=Fe,Co,Ti,V,等过渡金属元素),(δ=2/5,1/2)的结构和磁性

摘要: 总结了稀土金属(R)与过渡金属(T)化合物RT₅型系列衍生物中R₃(Fe,M)₂₉和R(Fe,M)₁₂的结构和内禀磁性,以及它们之间的关系.阐述了稳定元素(M)和嵌入轻原子(N,C,H)对其结构和内禀磁性的影响。

Abstract: Structure and magnetism of the R₃(Fe, M)₂₉ and R(Fe, M)₁₂ compounds derived from RT₅ with CaCu₅ -type structure (R=rare earth, T=Fe, and M=stable element) and the relationship between them are summarized. The influence of the stable elements and interstitial atoms(N, C and H)on the structure and magnetism of the R₃(Fe, M)₂₉ and R(Fe, M)₁₂ compounds are reviewed.
