✦ Synopsis

We report the effect of nearly hydrostatic pressure in the range 0-20 kbar on the resistively determined superconducting transition temperature Tc ofthe recently discovered infinite-layer electron-doped copper--oxide compound Sro a4NDo ,6CuO2. in contrast to other electron-doped copper oxides, we observe a positive and appreciable change in Tc with pressure with value dTJ dP--+0.06 + 0.02 K/kbar. Thus the sign and magnitude of d T¢/dP are not dominated by the carrier type; in this compound, we suggest they are determined by a pressure-induced enhancement oftbe interlayer coupling.

To differentiate between different theories of high-To superconductivity it is useful to spell out clearly their predictions before the experiments are performed. Here we make a prediction for the change in lattice constants of electron-doped oxide superconductors under hydrostatic pressure expected
