本文系统研究了R_2Fe_17_C(R=Y,Sm,Gd,Tb、Dy.Er) 化合物的结构与内享磁性, 井与相应的R_2Fe_17_C 化合物进行了比较.R_2Fe_17_C 的居里温度比相应氏R_2Fe_17 的居里温度增加大约200K. 本文讨论了C 原子对该化合物结构与磁性的影响, 同时, 还对Sm_2(Fe_1-xCo_x)_17C系列化合物进行了研充.We have studied the structure and intrinsic magnetic properties of R_2Fe_17_C compound (R=Y,Sm,Gd,Tb,DyandEr), and compounds them with the corresponding R_2Fe_17_ compounds. The Curie temperatures of R_2Fe_17_C are about 200K greater than those of R_2Fe_17_. We discussed the variation of the structure and magnetism of the compounds due to introducing C atoms. Furthermore, Sm_2_(Fe_1-x_Co_x_)_17_C compound have also been studied.
