Pressure Effect on the Superconducting Transition Temperature for (YxBa1-x)CuO2.3 Compound System

Abstract
The presure effect on the superconducting transition onset temperature (T co) and complete transition temperature (T cf) was measured for the compound (Y x Ba1-x )CuO2.3 with x = 0.325, 0.35 and 0.425. Both T co and T cf increase with increasing pressure. The values of dT co/dP and dt cf/dP are in the range of 0.09 to 0.17 K/kbar and 0.20 to 0.40 K/kbar, respectively. These values decrease with increasing the concentration x.
