摘要
本文介绍了稀土铁金属间化合物 R_2Fe_(14)B 及其掺杂系列的制备方法和晶体结构;分析和讨论了它们的内禀磁性;同时也反映了目前国际上永磁材料的研究进展和方向.
This paper introduces the methods of the preparation and crystal structure for rare— earth iron intermatalllc eompounds R_2Fe_(14)B and their interstitial compounds.Meanwhile,the intrinsic magnetic properties of the compounds are analysed and discussed.From that,the progress and the direc- tion of international study on permanent magnet materials are indicated.
