摘要：

An equation for nonlinear magnetic diffusion is derived for high-temperature (high-T-c) superconductors by using the power law for the electric field/current density relationship in the flux creep regime. Limitation of the Bean's critical-scare model in a transient experiment is discussed, Some experimental evidence for magnetic diffusion in high-T-c superconductors is provided. Effects of dissipation and heating on magnetic diffusion are discussed. (C) 2000 Elsevier Science B,V. All rights reserved.
