测量了烧结SrRuO3的零场冷却(ZFC)和加场冷却(FC)的直流磁化强度和交流磁化率.交流磁化率-温度曲线的峰随外加直流偏场的增加向低温方向移动.继续增加直流偏场,一个峰分裂成两个峰,其中低温下的一个峰继续向低温方向移动,另一个高温处的峰却向高温方向移动.在不同频率下测量零偏场下的交流磁化率.随频率的增加,峰值减小;但峰的位置并没有像以前报道的那样向高温方向移动.可见,烧结SrRuO3并没有显示自旋玻璃行为.

Zero-field-cooled (ZFC) and field-cooled (FC) DC magnetization and AC susceptibility of sintered SrRuO3 were measured over the magnetic ordering temperature. The peak in susceptibility against temperature shifts to lower temperature when the bias field increases. As the field still increases, the peak breaks into two peaks. One peak still shifts to lower temperature; the other shifts to higher temperature. Zero bias field susceptibility was measured at different frequencies. The peak value decreases as the increase of frequency, but it does not shift to higher temperature as reported previously. The results show that SrRuO3 is not spin glass, but ferromagnet.
