Structural and magnetic properties of MgFe2O4 ceramic

Magnesium ferrite (MgFe2O4) is one of the important and versatile spinel ferrite (usually written as (Mg1−xFex)[MgxFe2−x]O4) having low saturation magnetization value, high resistivity and reproducible characteristics. The stoichiometric phase of MgFe2O4 was successfully prepared by ball milling assisted sintering process. XRD pattern of the sample shows the formation of stoichiometric MgFe2O4 phase. The HRSEM image shows a distribution of particle size. Vibrating Sample Magnetometer study at room temperature shows a hysteresis loop behavior with a low saturation magnetization of about 20 emu/g and a small coercivity value. The temperature versus magnetization curve shows the ferromagnetic to paramagnetic transition.
