Mismatch Induced Type Transition of a Superconductor
arXiv:cond-mat/0603263 · doi:10.1103/PhysRevB.75.012505
Abstract
We use the Ginzburg-Landau theory near the transition temperature in order to examine the behavior of an inhomogeneous superconductor in the presence of a magnetic field. We find that a transition from type I to type II superconductivity occurs. Furthermore we calculate the critical value of the mismatch and estimate the contributions of the fluctuations of the condensate and the higher order terms in the Ginzburg-Landau framework.
