【摘要】 基于推广的磁通热激发模型，我们提出了评估超导体中钉扎力的一个新方法，该方法用于一个统一的形式表达了温度，磁场以及电流密度对作用于磁通线上钉扎力的影响，它解释了超导体混合态的电阻行为，并很好地拟合了Ｂｉ－２２２３外延膜钉扎力的标度行为．更多还原

【Abstract】 Abstract We suggested a new expression for the pinning force based on the extended flux thermal exitation model,which can describe the temperature,current and magnetic field dependence of the pinning force in a consistent way. This model gives a reasonable explanation for the resistive behavior of the superconductors in the mixed state,and fits the scaling behavior of the pinning force in Bi-2223 epitaxial thin films quite well.更多还原
