The temperature dependent ultrasonic longitudinal and shear velocities propagated at 10 MHz in superconducting (Er}.xPrx)Ba2Cu30 6.9 (x — 0.0, 0.1 and 0.2) and nonsuperconducting ErBa2CuiO6.j were used to evaluate effective Gruneisen parameters (yeff) for both modes. The elastic behavior of (Er1-xPr...
