Abstract

The recently discovered PrBa₂Cu₃O_y, superconductor possesses remarkable properties. The superconducting transition temperature T_c has been found to exceed 100 K under a pressure over 8 GPa and still have a pontential increase. We show that the extended t- J model with d-wave pairing for high-T_c superconductivity can explain the unusual pressure dependence of T_c in PrBa₂Cu₃O_y, by taking into account the variations of the hole concentration in the CuO₂ planes and the effective interaction with pressure. We suggest further experiments to enhance T_c at ambient pressure in PrBa₂Cu₃O_y.
