Influence of Pr substitution on acoustic gruneisen parameter and lattice vibrational anharmonicity contribution in ceramic superconductors
This paper reports the effect of Pr substitution on lattice anharmonicity contribution to temperature dependent longitudinal and shear ultrasonic velocity data in (Er1-xPrx)Ba2Cu3O 6.9 (x 0.0, 0.1 and 0.2) and TlSr2(Ca1-yPr y)Cu2O7 (y 0.5 and 1.0) superconductors. Pr was observed to influence the de...
