摘要：

Measurements of the superconducting transition temperature, T-c, under hydrostatic pressure via bulk AC susceptibility were carried out on several concentrations of phosphorous substitution in BaFe2-(As1-xRx)(2). The pressure dependence of unsubstituted BaFe2As2, phosphorous concentration dependence of BaFe2(As1-xPx)(2), as well as the pressure dependence of BaFe2(As1-xPx)(2) all point towards an identical maximum T-c of 31 K. This demonstrates that phosphorous substitution and physical pressure result in similar superconducting phase diagrams, and that phosphorous substitution does not induce substantial impurity scattering.
