Sol-gel auto combustion was used to create cerium doped Ni-Cr-Fe spinel ferrite nanoparticles. The cubic spinel structure with co-existence of the CeO2 and Fe2O3 phases is revealed by the XRD patterns of the samples sintered at 600 0C. When Ce4+ ions are added to nickel ferrites, the average lattice constant increases from 8.244 to 8.354 as the crystallite size increases. The well-defined and primarily spherical-shaped grains on the samples' surfaces are visible in SEM micrographs. All of the materials' infrared spectra were captured at room temperature in the 300–800 cm-1 range. The infrared spectra of the current samples also exhibit two major absorption bands, which is a characteristic of spinel ferrites. As the cerium content of Ni-Cr ferrite rises, saturation magnetization (MS) and remnant magnetization (Mr) decline.
