Abstract

Measurements of the superconducting transition temperature, Tc, under hydrostatic pressure via bulk AC susceptibility were carried out on several concentrations of phosphorous substitution in BaFe2-(As 1-xPx)2. The pressure dependence of unsubstituted BaFe2As2, phosphorous concentration dependence of BaFe2(As1-xPx)2, as well as the pressure dependence of BaFe2(As1-xP x)2 all point towards an identical maximum Tc 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.
