摘要：

Measurements of the superconducting transition temperature T(c) vs purely hydrostatic pressure (P <0.6 GPa) on specimens of compositions YBa2-xLaxCu3O7-delta (0 less-than-or-equal-to x less-than-or-equal-to 0.14) and Yl-yCayBa2Cu3O7-delta (0 less-than-or-equal-to Y less-than-or-equal-to 0.06) yield an approximately linear relation between dT(c)/dP and the carrier concentration induced in the CuO2 planes by chemical substitution with dT(c)/dP ranging from -0.6 K/GPa (y = 0. 06) to +2.2 K/GPa (x = 0. 14). A simple phenomenological model clarifies the dT(c)/dP behavior and provides a physical origin for the observed anomalous peak in T(c) (P) at P approximately 4 GPa [Klotz, Reith, and Schilling, Physica C 172, 423 (199 1)].
