At the transition from normal to superconducting states there were anomalies of ultrasonic attenuation in single-phased specimens Bi2-xPbxSr2CaCu2Oy (Tcmid = 80K); and as the temperature was lowered below Tcmid, the attenuation decreased rapidly. At

Ultrasonic attenuation and velocity measurements down to 77K were performed on high Tc superconductor Y-Ba-Cu-O samples with different sintering procedures. The change of sound velocity was found near Tc in two samples which have density of 94% of th

The temperature dependences of ultrasonic attenuation and velocity in high Tc superconductor BiSrCaCuO were measured between 50k and 280k, using longitudinal and shear waves. Ultrasonic attenuation anomalies were found at 87k, 120k, 240k and 250k for

The temperature dependences of ultrasonic attenuation and velocity in a high Tc superconductor BiSrCaCuO were measured by the ultrasonic pulse echo method, in the temperature range 77–300 K. Ultrasonic attenuation anomalies were found at 95, 135, a
