在完全的Kim-Anderson临界电流密度模型的框架内,我们计算了浸入外场H= Hdc + Hac cos(ωt)中的II型超导体的初始磁化曲线和全磁滞回线,其中Hdc(≥0)为直流偏置场,Hac(>0)为交流场幅值。我们用HA(= Hdc + Hac)和H B(= Hdc-Hac)表示H的最大值和最小值
Within the construct of the complete Kim-Anderson model for the critical-current density, we have calculated the initial magnetization curves and full hysteresis loops of type-II superconductors immersed in an external field H=H dc +H ac cos(ωt), where H dc (≥0) is a dc bias field and H ac (>0) is an ac field amplitude. We denote the maximum and minimum values of H by H A (=H dc +H ac ) and H B (=H dc -H ac )
