摘要：

Measurements of the superconducting transition temperature Tc in the electron-doped copper-oxide compounds L2-xMxCuO4-y under pressure P to 20 kbar reveal that, in general, Tc decreases with P, in contrast to the behavior of hole-doped copper-oxide compounds. The quantity d lnTc/d lnV exhibits a dependence on Tc similar to that of hole-doped compounds, but opposite in sign, and can be as large as 24. Correlation of structural and transport properties indicates competition between interlayer and intralayer effects in these materials. © 1990 The American Physical Society.
