Abstract

Using C programming language, we have simulated the flux creep process in nonideal type-II superconductors. Global and local magnetization curves arecalculated and the logarithmic time dependence of local magnetic inductionB under a constant external field is examined. The effects of nonuniform pinning potential and self-organized criticality (SOC) model on the simulations are discussed. The results show that the main feature of flux creep is the relaxation effect. The form of hysteresis loops is dependent on the magnetic field sweep rate. SOC can account for the occurrence of fluctuation to a certain extent and nonuniform pinning potential can enhance the fluctuation.
