Abstract
We report the pressure dependence of superconductivity for hole-doped polycrystalline Pr0.75Sr0.25FeAsO by the resistivity study using high pressure cubic and diamond anvil pressure cells. The superconducting transition temperature is initially increased from 17 K (P=0) to 34 K (P=6 GPa) with positive pressure coefficient, which is remarkable among other pnictide superconductors. At high pressure, there is no incredible enhancement of T c; in other words, it has a negative pressure effect on superconductivity, like in an electron-doped compounds. A systematic investigation of superconductivity for this 1111 type hole-doped iron pnictides is further carefully analyzed and discussed in detail using superconducting phase diagram under high pressure chart.
