Superconducting Anisotropy in Undoped and Pd-doped SrPt₂As₂

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 T_C from 5 K to 4 K, with a reduction in superconducting anisotropy and a possible suppression of the charge density wave onset temperature T_CDW.
