We report the growth, structural characterization, and magnetic properties of ferromagnetic Fe(0.8)Ga(0.2) nanowires that are grown on quartz substrates by electrospinning. Electrospun nanowires are annealed in ultrahigh purity argon-hydrogen gas mixture. Uniform, continuous, high aspect ratio FeGa nanowires with diameters in the range of 50-500 nm and lengths of up to 500 mu m are grown. Hysteresis loops were measured with magnetic field applied perpendicular and parallel to the substrate plane at 4 and 300 K. The nanowires exhibit a quite large coercivity (380 Oe) at 4 K in the parallel field. At 300 K, they show lower coercivities than that of bulk FeGa in both directions.
