Anomalous elastic response has been observed in superconducting HoBa 2-xHoxCu3O7-? (x = 0 and 0.15) from temperature dependent ultrasonic velocity measurements between 80 and 270 K. Longitudinal velocity of superconducting HoBa2Cu3O 7-? (Tczero ? 89 K) showed an anomaly around 230 K indicating a pro...
