Abstract
The nonlinear dynamics of magnetic flux, moving in a vortex-free super conductor is considered. It has been shown that the time dependent cha racteristic size R of magnetic flux domains is described by the scalin g behavior R similar to t(nu), where nu = 1/4 for circular droplets an d nu = 1/3 for elongated asymmetric droplets. These domains possess a sharp magnetic flux front and exist for a macroscopic long time in con tradiction with usual diffusive behavior. (C) 1997 Published by Elsevi er Science Ltd.
