Preparation and characterization of NiFe2O4 nanoparticles

Ni-Ferrite (NiFe2O4) nanoparticles haves been synthesized by simple and low cost co-precipitation technique. The synthesized product was characterized by X-ray diffraction (XRD), High resolution scanning electron microscopy (HRSEM) and vibrating sample magnetometry (VSM). The XRD and HRSEM results showed that the average particle size of the synthesized product was 20–25 nm with inverse spinel structure. The morphology of as synthesized product was in spherical shape. The existence of ferromagnetic properties was confirmed by VSM.
