Formation of superconducting A ‐15 V 3 Ge compound by a composite‐diffusion process Academic Article uri icon


  • Superconducting A-15 V3Ge is formed by the V/Cu-Ge composite-diffusion process. Copper from the Cu-Ge alloy matrix enhances the formation of V3Ge but does not dissolve in the V3Ge. The highest transition temperature obtained, 7.1 K, is slightly higher than the value reported for arc-melted V3Ge. An off-stoichiometric composition of about 21.7 at.% Ge was found in the A-15 layer, indicating the possibility of Tc enhancement in V3Ge, as in the case of Nb 3Ge.
