CONTRIBUTION TO THE THEORY OF SUPERCONDUCTING ALLOYS WITH PARAMAGNETIC IMPURITIES (in Russian)
It was demonstrated within the framework of superconductivity theory that the transition temperature, T/sub c/, of a superconductor with paramagnetic impurities is lower than that of a pure metal. The dependence of T/sub c/ on the impurity concentration was determined. At a certain critical concentration the superconductivity disappeared. The thermodynamic and magnetic properties of superconducting alloys in a concentration range close to the critical value were studied in detail. It was found that for T yields O there is no exponential term in the expression for the heat capacity in this region. The concentration dependence of the energy spectrum gap of such a system was determined. It was found that for a concentration n' approx equal 0.9 n/sub cr/ the gap disappears and at large concentrations the system has a continuous spectrum. (auth)
