The interaction of electrons with magnetic impurities in superconducting magnetic alloys is calculated to second order in the spin exchange coupling. Its effects on the transition temperature, the order parameter, the density of states, and the conductance are studied. The results are as follows. (1

## Abstract A general formula for the energy difference between superconducting and normal states of an alloy with paramagnetic impurities is developed on the basis of the ShibaβRusinov theory. The result is used to calculate the thermodynamics of the alloys InβMn, InβCr, and PbβMn. It is shown tha
The single-impurity speciΓΏc heat ci(T ) and impurity susceptibility i (T ) of an extended s-d Hamiltonian H are derived and examined in the vicinity of the transition temperature Tc. ci(T ) is found by exploiting the single-impurity solution of H due to Andrei et al., whereas i (T ) by applying seco
