摘要:	在本研究中,我们以射频产生器产生氢电浆的方法对钇钡铜氧粉末做氢化处理,并做磁特性量测.由直流磁化率量测之结果显示,粉末的抗磁性增加, 临界温度不变.此结果和过去许多用高压氢气直接反应所得之实验结果不同.为膫解氢化效应对抗磁性增加的机制,我们又做交流磁化率和 MAGNETZATION RELAXATION 测量,指出氢电浆反应法所造成的结果并不属性于质子照射产生的钉扎效应. We report that the dimagnetism of YBCO powers can be enhanced by treatment with RF-generated hydrogen plasma. Both the field- cooling and zero-field-cooling susceptibility measurement at 5 K are found to tent to increase. Further, by the ac susceptibility measurement and magnetization relaxation measurement, we indicate that the enhancement of diamagnetism and irreversible magnetization is not purely due to proton -irradiation-like pinning effect, but other hydrogen effect.
