Ferrites have been used in various electronic applications, energy applications, and magnetic interference. In recent years, a number of chemical synthesis methods have been developed to prepare various magnetic ferrites depending on the size, composition, surface chemistry, and aggregation state. In this work, magnesium-doped nickel ferrites nanoparticles with chemical formula Ni1-xMgxFe2O4 (were, x= 0.0, 0.1, 0.3, 0.5, and 0.7) were synthesized at temperature (700ºC) and pH=11 using chemical co-precipitation thermal method. The powder XRD pattern confirms single-phase cubic structure and the average particle size calculated by Scherer equation ranged between (19-29 nm) based on X-ray diffraction. The surface morphology and elemental composition were studied by Scanning electron microscope (SEM) and Energy Dispersive X-ray analysis (EDX) respectively. The SEM analysis shows the increasing the proportion of magnesium to shifted the morphology into particles with spherical. This work introduces novel and valuable synthesis route for preparation and morphological controlling of Ni1-xMgxFe2O4.
