Superconductivity in the CuAl₂ (C16) crystal class

Abstract

Several superconducting compounds have been found in the CuAl2 (C16) crystal class, indicating that this structure is among those favorable to the occurrence of superconductivity. The compounds were: AuPb2 (Tc = 4.42°K), PdPb2 (Tc = 2.95°K), RhPb2 (Tc = 2.66°K) and Agln2 (Tc = 2.30-;2.46°K). In addition, two compounds related to the C16 class were found to be superconducting: AuSn4 (Tc = 2.38°K) and PtPb4 (Tc = 2.80°K). © 1962.
