Synthesis of Nickel Ferrite (NiFe₂O₄) Nanoparticles by the Hydrothermal Method

Abstract

In this study, nickel ferrite (NiFe2O4) nano-crystallites with an average diameter of 46.01 nm are synthesized via hydrothermal method. The single-phase spinel structure is confirmed by X-ray diffractograms (XRD). Morphology is analysed by scanning electron microscopes (SEM) and energy dispersive X-ray (EDX) analysis was used to determine the elemental composition of the materials. The magnetic properties of the nanoparticles are studied by vibrating sample magnetometer (VSM) and the results exhibited superparamagnetism at room temperature with the magnetic saturation of (Ms) 39.8 emu/g.
