Abstract

Propagation of longitudinal waves at 740 MHz in superconducting amorphous Pd30Zr70 has been studied between 0.4 K and 70 K. No change of the absorption occurs when passing through the superconducting transition temperature at 2.62 K whilst a strong decrease is found for temperatures from 1.5 K down to 0.4 K. Below 1.5 K a strong magnetic field dependent enhancement of the acoustic attenuation is observed. We compare these results with a recently developed theory.
