The spin exchange interaction effect on Tc equation of anisotropic impure superconductors

Abstract

We study the influence of spin exchange interaction of impurity scattering on critical temperature of anisotropic impure superconductors. The model of random non-magnetic and magnetic impurity are revised to cover the effect of spin exchange interaction. The sign of magnitude of the second-order Born scattering has been changed after consideration of the spin exchange interaction that also effects the form of Tc equation. We can get the general Tc equation that can be described well by anisotropic impure superconductors and covers all models done before. © 2008 Elsevier B.V. All rights reserved.
