Abstract

Ultrasonic longitudinal and shear wave velocities were measured for superconducting and non-superconducting DyBaSr Cu3O7-δ (Dy-1113) at 10 MHz between 80 and 270 K. The superconducting sample exhibits a step-like elastic anomaly between 190 and 230 K. No elastic anomaly was observed in the non-superconducting Dy-1113. The anomaly observed in the superconducting sample is attributed to structural phase transition caused by oxygen orderings.
