Abstract

The elastic properties and ultrasonic attenuation of TlSr2(Sr0.5Y0.5)Cu2O7 have been determined between 80 and 280 K at frequencies in the 10 MHz region. Electrical resistance versus temperature measurement showed that the critical temperature is 88 K. Ultrasonic measurements showed a change in longitudinal velocity gradient and the attenuation peak around 200 K. The results were explained in terms of the phase transition associated with local oxygen ordering. The shear velocity showed an almost monotonic increase between 220 and 80 K and no attenuation peak is observed in this mode.
