Abstract
The acoustic attenuation coefficient, the nuclear spin relaxation rate, and the electronic thermal conductivity of superconducting magnetic alloys are calculated in the weak-coupling theory developed in a previous publication. This theory generalizes the Bardeen-Cooper-Schrieffer theory of pure superconductors by considering a finite electron lifetime arising from magnetic impurity scattering. The transport coefficients are expressed as two-electron Green's functions and evaluated in the independent-particle approximation.
