Numerical Simulation of Flux-Creep in HIGH-TC Superconductors

Anderson theory is modified to explain features of the flux creep in high-T_c superconductors. The approach is based on a consideration of single-vortex pinning and creep in a washboard potential with the presence of normal pinning strength distribution. It explains the results of the studies of flux creep in high-T_c superconductors. Quantitative agreement between the model and the experimental data for different high-T_c superconductors can be obtained.
