Record superconductor at 22.3 K

OCT 01, 1973

DOI: 10.1063/1.3128271

Ronald J. Cohn

A new record‐high superconducting transition temperature, $T_{c} = 22.3 K$ for ${Nb}_{3} Ge,$ was announced recently. This temperature is, most significantly, more than two degrees above the boiling point of hydrogen; a significant step may therefore have been taken to move superconductivity applications from a technology based on liquid helium to one based on liquid hydrogen. The previous high transition temperature reported was 20.98 K for a Nb–Al–Ge pseudobinary alloy.
