Superconducting and Antiferromagnetic Properties of Dual-Phase V${}_3$Ga

Abstract

The binary compound V${}_3$Ga can exhibit two near-equilibrium phases, consisting of the A15 structure that is superconducting, and the Heusler D0${}_3$ structure that is semiconducting and antiferromagnetic. Density functional theory calculations show that the two phases are closely degenerate, being separated by only ~10 meV/atom. Magnetization measurements on bulk-grown samples show superconducting behavior below 14 K. These results indicate the possibility of using V${}_3$Ga for quantum technology devices utilizing both superconductivity and antiferromagnetism at the same temperature.
