Abstract:Powder mixtures of (99.9% pure) FeCl2 and CoCl2 were used for synthesis of nanostructured Fe–Co alloy powders by chemical solution mixing and hydrogen reduction (CSM-HR). Nano-sized Fe–Co alloy powders were successfully fabricated by CSM-HR. The CSM-HR synthesized Fe–Co powder showed an ordered α′ phase with a particle size of 45 nm. The synthesized SMHR powder exhibited a coercivity force of 36 Oe and saturation magnetization value of 214 emu/g.
