High superconducting transition temperatures in the palladium-noble metal-hydrogen system

  • Published:
Zeitschrift für Physik

Abstract

High superconducting transition temperatures, Tc, of 16.6, 15.6 and 13.6 K have been observed in Pd-(Cu, Ag and Au) alloys, charged with large amounts of H by means of ion implantation at liquid Helium-temperatures. A peculiar phase-transition indicates that weak phonon modes might be responsible for the high Tc-values. The difference between the maximum Tc-values can be described as a type of isotope effect Tc∞M −1/2.
