Relaxation of normal spot in type-II superconductors
Institute of Superconductivity, Department of Physics, Bar-Ilan University, Ramat Gan 52900, Israel
Accepted: 22 September 1998
Relaxational dynamics of the non-equilibrium normal domain in a superconductor is considered. It is shown, both analytically and numerically, that this relaxation leads to nucleation of topological vortices and antivortices. In the presence of strong pinning such a vortex/antivortex phase persists infinitely.
