Abstract

Ultrasonic longitudinal and shear velocities propagated at 7-10 MHz in bulk Tl2Ba2Ca2Cu3O10 have been measured between 80 K and 300 K. Shear velocity measurements revealed a pronounced slope discontinuity of 421 ppm/K at around 160 K. A similar slope change was not observed in the longitudinal mode. The slope change around 160 K for the shear mode is suggested to be attributed to some form of correlated Tl and O(4) orderings in the material.

Shear velocity measurements revealed a pronounced slope discontinuity of 421 ppm/K at around 160 K. A similar slope change was not observed in the longitudinal mode. The slope change around 160 K for the shear mode is suggested to be attributed to some form of correlated Tl and O(4) orderings in the material.
