【摘要】 在低于T_c较远的温度下,发现金属玻璃Zr₇₈Co₂₂带在纵向磁场中的I-V和H-V特性曲线上存在着两类电压跃变阶梯。与以往在准一维或准二维均匀超导体中发现的I-V曲线上出现阶梯结构的条件和特点作了系统的比较,综合应用超导相分离模型和由热涨落诱发的相位滑移中心的概念解释了所观察到的现象。更多还原

【Abstract】 When the temperature is far below Tc, a set of electric voltage steps appear on the H-V or I-V curves of the metallic glass Zn₇₈Co₂₂ under longitudinal magnetic fields. The oc-curing conditions and the structural characteristic of steps have been compared systematically with the steps existing in homogeneous superconductors of quasi-one or quasi-two dimension systems. A model of superconducting phase separation and the idea of phase slip centers have been used to explain the observed phenomena.更多还原
