Pressure dependence of superconducting critical temperature ofSr2RuO4

Abstract

We studied electrical resistivity of single crystals of an oxide superconductor Sr{sub 2}RuO{sub 4} under hydrostatic pressure up to 12 kbar. The midpoint T{sub c} decreases at the rate of 3{percent}/kbar. Anomalous increase of resistivity along the c axis is observed at room temperature with increasing pressure, whereas that in the ab plane decreased with pressure as normally expected. {copyright} {ital 1997} {ital The American Physical Society}
