Open publisher page 1 citations

Abstract

The effect of an applied magnetic field on an inhomogeneous superconductor is studied and the value of the lower critical magnetic field H, at which superconducting vortices appear is estimated. In addition, the authors locate the vortices of local minimizers, which depends on the inhomogeneous term a(x).
