Pure chromium nanoparticles with the general formula CrFe2O4 have been produced using the conventional wet chemical co-precipitation process. For four hours, the prepared sample was annealed at 600 0C. The generated sample's room-temperature X-ray diffraction patterns were acquired to verify the creation of a single-phase cubic spinel structure. The surface morphology of the manufactured samples was examined using scanning electron microscopy. The results of the XRD and SEM examinations indicate that the particles' sizes are in the nanometer range. The specified range of the lattice constant was met. The magnetic characteristics were investigated by means of the pulse field hysteresis loop approach. It was discovered that the coercivity and saturation magnetization were greater than those in bulk.
