Critical field of a type-I spherical superconducting inclusion

Abstract

The method of critical magnetic field calculation for a type-I superconducting spherical inclusion was developed. The dependence of the critical field on the inclusion radius was calculated for different types of boundary condition. The proposed method gives the possibility to determine the value of the critical field Hc(R,b) with any desirable accuracy.

Giant vortex structures in nanometer-scale spherical type-II superconducting samples

“…(1) With increase of the radius of a spherical sample the number of possible vortex states increases. It is obvious that the critical magnetic field decreases on increasing the radius of a spherical inclusion [27], [28]. (2) The values of the ground-state field intervals are decreased with the increase of the spherical inclusion radius.…”
