AbstractAmorphous FeNiP nanoparticles with homogeneous composition are synthesized by reduction of aqueous Fe2+ and Ni2+ with sodium borohydride (NaBH4) and hypophosphite at room temperature. These amorphous nanoparticles can be crystallized by heating up to 300 degrees C to form FeNi3 and Ni3P crystals. Ni phase appeared at the sintering temperature of 500 degrees C, and a special net structure was formed at 700 degrees C due to the joining and diffusion among different nanoparticles. At a higher temperature of 800 degrees C, phase transformation happened and only pure Ni nanospheres and monoclinic ((Ni, Fe)(3)[PO4](2)) nanorods can be observed, which should be governed by the long-range diffusion in the net structure. The amorphous FeNiP nanoparticles have excellent soft magnetic property with Ms of 13.2 emu/g and He of 0.7 Oe. However, the sintered mixing nanoparticles show varied magnetic properties due to the phase transformation and proportion change among different phases involved in.; Amorphous FeNiP nanoparticles with homogeneous composition are synthesized by reduction of aqueous Fe2+ and Ni2+ with sodium borohydride (NaBH4) and hypophosphite at room temperature.
