Structural and Magnetic Properties of Nanocrystalline Ni-Fe Ferromagnetic Alloy

Abstract

The simple and cost effective liquid-solid interaction chemical method is developed to prepare nanocrystalline NixFe100-x (x = 73) alloy powder. NiCl2.6H2O and FeCl3 were directly reduced using aluminum at room temperature in aqueous medium. The X-ray diffraction (XRD) measurements were carried out on Ni73Fe27 alloy powder. Ni73Fe27 alloy shows the FCC phase. The average crystalline size of Ni73Fe27 alloy powder was found that 8 nm from Sherrer’s method. The magnetization of Ni73Fe27 alloy nanoparticles was 88.6 emu/g. The alloy formation and Curie temperature of Ni73Fe27 alloy particles also will be studied and reported in future communication.
