Abstract

We have calculated the electromagnetic absorption of superconducting alloys containing paramagnetic impurities in the model of Shiba and Rusinov. A peak in the absorption is found to appear at low frequencies and finite temperatures, the temperature variation of which may be useful in determining appropriate phase shifts for particular alloys. The absorption is calculated for Pb-Mn and Zn-Mn alloys using scattering phase shifts derived from tunneling experiments. In the case of Pb-Mn, only one of the two candidate parameter sets is found to be consistent with existing experimental results.
