The properties of Electrical Resistance in Cu100-xZrx Metallic Glasses System under Pressure Loading
-
摘要: 本文在0~0.8 GPa的压力范围内对金属玻璃Cu100-xZrx（x=70，75）进行了室温下的电阻测量。利用实验得到的负的电阻-压力系数p及推广的Ziman理论着重计算并讨论了压力下d波相移2(EF)项对p的贡献。Abstract: The pressure dependence of electric resistance for Cu100-xZrx (x=70, 75) metallic glasses has been measured under pressure from 0 to 0.8 GPa and at room temperature. In two samples, the pressure coefficients of resistance p are negative. The contribution of d-wave phase shift 2(EF) under pressure loading to p are calculated and discussed with the measured value of p and generalized Ziman theory.
