Superconductivity in palladium-noble metal-hydrogen systems

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

The apparently puzzling observations in the superconducting behavior of palladium—noble metal—hydrogen (deuterium) systems, viz., the occurrence of higherT c and a monotonic increase inT c for Au, Ag and Cu systems; the absence of the H(D) induced opposite isotope effect; the existence of an optimum noble metal content, different for different alloy systems, beyond which superconductivity ceases; and the existence of an optimum hydrogen content, different for different alloys, giving the highestT c , have been accounted for by taking due cognition of the electronic and the crystallographic behavior of these alloys and their role in superconductivity, the participation of H(D)-optic phonons, in conjunction with anharmonicity, in BCS-type pairing interaction and the manifestations of the metallurgical and thermodynamical properties of these alloys in superconductivity.
