Different Temperature Dependence of the Phase Boundary for Multivortex and Giant Vortex States in Mesoscopic Superconductors

摘要

Within the framework of the nonlinear Ginzburg-Landau theory, we calculated the full phase diagram for a superconducting disk with radius R velence 4xi(T velence 0) and we studied the behavior of the penetration and expulsion fields as a function of temperature for multivortex and giant vortex states.
