摘要
研究了Nd6 0 Al1 0 Fe2 0 Co1 0 大块金属玻璃磁性随温度的变化关系 ,结果表明Nd6 0 Al1 0 Fe2 0 Co1 0 在室温下表现为永磁性 ,随着温度的降低 ,矫顽力和磁滞回线形状都有很大的变化 .交流磁化率在 18K左右出现尖峰而且峰值温度随频率变化 。
The temperature dependence of magnetic properties for Nd60Al10Fe20Co10 bulk metallic glass is investigated. The results indicate that the Nd60Al10Fe20Co10 bulk metallic glass exhibits permanent magnetic behaviour at room temperature. The coercive force and the shape of hysteresis loops change markedly when temperature decreases. AC magnetic susceptibility is measured and a peak at about 18K is found. The peak moves torwards high temperatures when the frequency is increased. This indicates that there are spin glass structures in the bulk metallic glass.
