Description
Ultrasonic study on single phase (Bi0.85Pb0.15)2Sr2Ca2Cu3O10+x revealed that there are isothermal-like anomalies near 210 K in both velocity and attenuation of longitudinal and transverse sound waves. Specific heat measurements also showed clear anomaly at about 210 K, suggesting the occurrence of some structural changes or phase transition. Comparing with YBa2Cu3O7-y, possible mechanisms are discussed
