摘要：

We have measured the resistivity of electron-doped superconductors Ln1.85Ce0.15CuO4-y (Ln = Nd, Sm, Eu) under quasihydrostatic pressure up to 100 kbar. All the samples remain superconducting for this pressure. The ratio d log T(c)/d log V was found to be of the same order of magnitude as the one measured under hydrostatic pressure up to 20 kbar, weak and positive, in contrast with the hole doped high T(c) superconductors. The effect of applied pressure on T(c) does not compare with that of chemical pressure.
