Doping of metal ions in magnetic iron oxide particles can improve its performance and lead to its new technological and industrial applications. Magnetic iron oxide particles of undoped and cobalt doped were synthesized from natural sand of Logas District Kuansing Regency by ball milling method. The structural properties and the morphology of the magnetic iron oxide F e2O3 particles were analyzed using X-Ray Diffractometer (XRD) and scanning electron microscope (SEM). The X-ray diffractometric study showed that X-ray diffraction (XRD) peaks shift to slightly higher angles as compared to those of undoped magnetic iron oxide particles. This shift is due to relatively smaller ionic radius of cobalt as compared to those for iron. Moreover, peaks corresponding to cobalt oxide or metal cobalt could not be observed in the diffraction pattern. Some other diffraction peaks from other crystalline forms such as silicon (Si) and titanium (Ti) were observed.
