Influence of Co-Precipitation Method on Structural and Magnetic Properties of Nickel Ferrite Nanoparticles Prepared

Abstract
In this research work, we have prepared nickel ferrite nanoparticles by using chemical route. Nanoparticle materials are characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), vibrating sample magnetometer (VSM), scanning electron microscope (SEM) and energy dispersive X-ray (EDX) systems. We have determined magnetic properties, size, purity, stoichiometry and morphology of samples. The samples are calcinated at different temperatures, then we found that size of particles increase with heating and powder transfer from amorphous to crystalline phase of nickel ferrite. The crystallite size of particles for samples that calcinated at 400 and 600°C obtained 46.2 and 70 nm by using Sherer's formula, respectively.
