摘要
使用ＬＣＡＯ对永磁系列Ｙ２Ｆｅ１７Ｃｘ（ｘ＝０，１，２，３，）的电子结构计算结果，计算了该系列模型材料的居里温度，并和基底材料Ｙ２Ｆｅ１７作了对比．居里温度的增长系数和实验符合较好．
The Curie temperatures of series modle materials Y2Fe17Cx(x=0,1,2,3)are calculated using LCAO calculsted results of the electronic structure of these permanent magnets,and a comparison is carried oat with ha material Y2Fe17. The increasing values of Curie temperature are in good agreement with the experimments.
