Abstract： The effects of flux creep on the magnetization curves of high-temperature superconductors are investigated numerically for Anderson-Kim model. The pinning energy at zero current density, Uc, greatly influences the flux penetration process, a larger Uc, value reults in a larger penetration field. The characteristic of the magnetization curve is also a function of Uc. The magnetization M and ΔM increase with the increasing Uc and depend on the magnetic induction B, so the critical current formula based on Bean model is pot accurate, especially for high-Tc superconductor, for which flux creep is a large effect.
