Abstract

Damping of ultrasonic longitudinal vibrations in the superconducting (BiPb)₂Sr₂Ca₂Cu₃O_y, ceramic has been studied in the 6-290 K temperature range by the composite oscillator technique at vibrational strain amplitudes of up to 3 × 10^-5. The amplitude-dependent internal friction, which is observed to exist at both room and helium temperatures, was found to be practically absent in the 100-140 K interval. The results obtained are attributed to specific features of dislocation motion in this material. Data on the effect of magnetic field on the acoustic characteristics at 7 K are presented.
