Recently, we succeeded in developing new V<sub>3</sub>Ga multifilamentary wires fabricated via the Powder In-Tube (PIT) process using high Ga content Cu-Ga binary phase compounds. We also found that high Ga content in the precursor promoted the formation of the stoichiometric V<sub>3</sub>Ga phase and it was effective in improving superconducting properties.</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Keywords : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>annealing; critical current density (superconductivity); crystal microstructure; multifilamentary superconductors; stoichiometry; superconducting magnets; titanium compounds; vanadium compounds; TiGa<sub>3</sub>; V<sub>2</sub>Ga<sub>5</sub>; V<sub>3</sub>Ga; arc-melting; fusion reactor system; hand-milling; microstructure; multifllamentary wires; post-annealing; powder in-tube process; radioactive decay time; stoichiometry; superconducting magnet materials; Compounds; Copper; Gallium; Heat treatment; Powders; Superconducting magnets; Wires; <formula formulatype=$ ${rm V}_{2}{rm Ga}_{5}$; ${rm TiGa}_{3}$; ${rm V}_{3}{rm Ga}$ compound; High Ga content compound; PIT process; low activation;
