Abstract
A peak of acoustic emission (AE) is observed experimentally at the sup erconducting transition temperature in samples of the superconducting ceramics Tl2Ba2CuO6+x. AE signals have been recorded by a piezoelectri c transducer with the resonant frequency 1 MHz in the temperature rang e 80-300 K. Relaxation anomalies are attributed to a change in the cha rge state of linear defects and variations of the parameters of the cu prate layer in the samples. (C) 1998 American Institute of Physics.
