It was found that as temperature increases, the easy direction of magnetization changes gradually from [110] to [111] axis in the temperature range of 153 to 213 K. Two easy directions of magnetization [110] and [111] coexist and do not change suddenly from [110] to [111] at the same temperature.展开更多

文摘By Mossbauer-effect, the changes of easy direction of magnetization for Sm0.88Dy0.12.Fe2 alloy have been studied in this paper. It was found that as temperature increases, the easy direction of magnetization changes gradually from [110] to [111] axis in the temperature range of 153 to 213 K. Two easy directions of magnetization [110] and [111] coexist and do not change suddenly from [110] to [111] at the same temperature.
