Abstract

The time-dependent Ginzburg–Landau equations have been solved numerically by a finite-element analysis for a mesoscopic superconducting ring structure. For given applied magnetic fields we have simulated the dynamical behavior of the penetrating magnetic vortices into the superconductor. Moreover, we investigated the vortex configurations and found a vortex state with two stable vortex shells in the mesoscopic superconducting ring due to the enhanced surface superconductivity.
