Abstract
The superconductivity of phases rich in the noble metals (Cu, Ag, Au) was investigated. All face-centered cubic solid solutions (with Zn, Cd, Al, In) remained normal down to 0.014°K; and all hexagonal close-packed phases (with Si, Ge, Sn, Sb, Al, In) became superconducting in the range of 0.019-0.61°K. The results are interpreted as due to the Fermi-surface-Brillouin-zone interaction. The first superconductor with a structure was found in the alloy Cu-15.5 at.% Sb.
