Abstract

We report the results of our investigation of SrPt3P, a recently discovered strong-coupling superconductor with Tc=8.4 K, by application of high physical pressure and by chemical doping. We study hole-doped SrPt3P, which was theoretically predicted to have a higher Tc, resistively, magnetically, and calorimetrically. Here we present the results of these studies and discuss their implications.
