Superconducting Anisotropy in Undoped and Pd-doped SrPt<sub>2</sub>As<sub>2</sub>

POSTER

Abstract

SrPt2As2 is a nonmagnetic analogue of iron-based superconductors, like those derived from BaFe2As2. SrPt2As2 is of particular interest as it is reported to show charge density wave formation well above room temperature. We show that Pd-for-Pt doping in single crystal material suppresses the superconducting transition temperature TC from 5 K to 4 K, with a reduction in superconducting anisotropy and a possible suppression of the charge density wave onset temperature TCDW.
