Upper Critical Field and Critical Temperature for Superconducting Alloys Described by the Anderson Model.
Abstract
Extending some recent work by H. Shiba the authors have used the Hartree-Fock approximation for the Anderson Model of localized impurity electron states in a superconductor to obtain expressions for the critical temperature in zero magnetic field and for the upper critical field. The expression for the critical temperature reduces to Kaiser's result in the limit of no impurity magnetic moment, and Fulde and Maki's result in the magnetic limit. Between these two limits are found results which differ appreciably from those of either limit. (Author)
