The synthesis of low temperature phases by the CO-condensation of the elements: A new superconducting A15 compound, V3Al

Abstract

A method is described whereby intermetallic phases which are not stable at high temperatures may be formed using controlled vacuum evaporation of the elements. V3Al with the A15 structure was formed on substrates held at temperatures in the range 350-450°C. For the as-deposited sample the lattice parameter was 0.483 nm and the superconducting critical temperature was 9.6°K. © 1971.
