- 論文の詳細を見る
The spin freezing and random magnetic anisotropy in Tb-Fe-Si amorphous alloys have been investigated. Zero-field and field-cooled magnetizations of (Tb_<0.22>Fe_<0.78>)_<100-x>Si_x(0≤x≤10) amorphous alloys exhibit a magnetic cooling effect. The spin freezing itmperature decreases with ncreasing x. The compensation temperature is lower than the spin freezing temperature. The present amorphous alloys exhibit a negative magnetization because the frozen spins can not be turned over below the compensation temperature.
