摘要：

The nonlinear dynamics of magnetic flux, moving in a vortex-free superconductor is considered. It has been shown that the time dependent characteristic size R of magnetic flux domains is described by the scaling behavior R similar to t(nu), where nu = 1/4 for circular droplets and nu = 1/3 for elongated asymmetric droplets. These domains possess a sharp magnetic flux front and exist for a macroscopic long time in contradiction with usual diffusive behavior. (C) 1997 Published by Elsevier Science Ltd.
