摘　　要：运用穆斯堡尔效应，对Ｓｍ０．８８Ｄｙ０．１２Ｆｅ２合金的易磁化方向的变化进行了研究。结果表明：随着温度的升高，其易磁化方向从［１１０］渐变地转向［１１１］，在１５３至２１３Ｋ温度范围内，［１１０］和［１１１］两者共存，而并非由［１１０］在某一温度突变至［１１１］。By Mossbauer-effect, the changes of easy direction of magnetization for Sm0.88Dy0.12Fe2 alloy have been studied in this paper. It was found that as temperature inerease, the easy direction of magnetization changes gradually from [110] to [111] axis , in 153 K to 213 K temeprature interval,two easy directions of magnetization [110] and [111] coexist and do not change suddenly form [110] to [111] at one temperature.
