Superconductivity in epitaxial PtSb(0001) thin films
This study reports the discovery of type-II superconductivity in epitaxial PtSb(0001) thin films grown on SrF2(111), characterized by a transition temperature of 1.72 K, anisotropic upper critical fields, and significant critical current densities, establishing PtSb as a promising platform for heterostructures within the NiAs-type materials family.
