摘要：

The Anderson-Kim model has been modified in terms of the U-j relationship for high-T(c) superconductors. We have obtained U-j curves by an approach based on the temperature dependence of j(c). Our results are consistent with the physical picture of flux creep. Our data is obtained from magnetic-relaxation experiments on YBa2Cu3Ox single crystals with the direction of the field parallel to the c axis. The decay of magnetization was studied for both increasing and decreasing fields, used to obtain the current density.
