In this work, the FeNi{sub 3} permalloy nanopowder was synthesized by wire explosion in deionized water. X-ray diffraction was used to identify and characterize the prepared nanopowder exhibiting a FeNi{sub 3} phase. The morphology and size of the prepared powders were observed by field emission-scanning electron microscopy and transmission electron microscopy. The compositions of the wire before exploding and the nanopowder were determined with electron probe microanalysis. The results indicate that the FeNi{sub 3} permalloy nanopowder was synthesized with an average particle size {approx}50 nm. The magnetic properties of the nanopowder indicate a symmetric hysteresis loop of ferromagnetic behavior with coercivity of 199.3 Oe and saturation magnetization of 56.7 emu/g.
