V3Ga crystallizes in the cubic Pm-3n space group. The structure is three-dimensional. V is bonded in a 6-coordinate geometry to two equivalent V and four equivalent Ga atoms. Both V–V bond lengths are 2.39 Å. All V–Ga bond lengths are 2.68 Å. Ga is bonded to twelve equivalent V atoms to form a mixture of edge and face-sharing GaV12 cuboctahedra.
Vanadium-gallium system in region of V-3Ga studied by X-ray diffraction and metallography techniques
The paper considers critical currents in A-15 structure Nb3Al converted from a cold-worked bcc structure. Nb3Al prepared in the ductile phase by quenching and mechanical working followed by conversion to the A-15 structure could carry currents above 10 to the 9th power A/sq m in fields near 20 T. These critical currents are comparable to those of Nb3Ge and V3Ga which are closest competing materials for use in high fields; further enhancement of the critical current is possible if thermal treatments are optimized.
