Abstract
The ultrasonic longitudinal sound wave attenuation coefficient and the nuclear spin relaxation rate have been calculated for a superconducting alloy containing paramagnetic impurities with local states within the gap. The Green's function given by Shiba (1968) or Rusinov (1969), which is appropriate for the case of a strong exchange interaction between the conduction electron spin and the magnetic impurity spin is used. For temperatures near Tc and for a low impurity concentration the authors also include the Kondo effect in their calculations. They find significant deviations from calculations based on the Green's function given earlier by Abrikosov and Gor'kov (1961).
