Abstract

The discovery, early development, and BCS theory of the ultrasonic attenuation in superconductors is reviewed. It is shown that the BCS formulation containing the concept of a superconducting energy gap leads to a satisfactory explanation of the temperature dependence of the attenuation for a wide range of superconductors. Emphasis is placed on recent measurements which exhibit drastic deviations from the simple behavior described by BCS. Experiments are reviewed on the amplitude dependence in attenuation associated with the motion of dislocations and on the influence of vortex lines on the magnetic field dependence of the attenuation in type II superconductors.
