Superconductivity in Binary Alloy Systems of the Rare Earths and of Thorium with Pt-Group Metals

Abstract

Superconductivity has been discovered in many binary systems composed of transition metals having nearly empty and nearly filled $d$ shells. With the exception of the Sc-Pt and Ce-Rh systems, all contain at least one superconducting phase and frequently more. By comparing the transition temperatures of analogous compounds, it is inferred that pure Rh should become superconducting above 10 mdeg and pure Pt at a considerably lower temperature.
