Abstract
We calculate properties of Kondo alloys in which superconductivity is induced by the proximity effect, taking account of the energy dependence as well as the temperature dependence of pair-breaking, using the phenomenological model of Müller-Hartmann, Schuh, and Zittartz. The reentrant behavior of the transition temperature is significantly reduced when the energy dependence of pair-breaking is included. The specific heat jump can distinguish between different theories of superconductivity in Kondo alloys. Measurements of the maximum dc Josephson current could indicate the temperature dependence of the order parameter and pair-breaking away from the transition temperature at higher impurity concentrations (a regime for which theoretical predictions are unreliable for both induced and intrinsic Kondo superconductors).
