Abstract
The attenuation of transverse sound waves in a superconductor containing transition-metal impurities whose behavior lies close to the magnetic-to-nonmagnetic transition is studied. Comparison is made between the attenuation coefficient obtained on the basis of the local spin-fluctuation (LSF) description of the system and the coefficient obtained on the basis of a high-TK Kondo impurity description of the system. It is seen that the LSF-based transverse attenuation coefficient can give a reasonable fit to the observed attenuation in superconducting ZnMn alloys (which are alloys lying very close to the magnetic-to-nonmagnetic transition), while the high-TK Kondo-description-based coefficient cannot.
