Abstract
We have measured the pressure dependence of the superconducting transi tion temperature of Sr2CuO2F2+delta to 5 kbar using He as the pressure medium. Qualitatively different derivatives are obtained for pressure changes at 300 K and 50 K with the anomalous result that the 50 K val ue is negative instead of the usual small positive value seen for othe r copper-oxide based materials.
