Abstract
The magnetic material of Manganese Ferrite (MnFe2O4) based on natural Iron sand have been successfully prepared by using co-precipitation method. The natural Iron sand, MnCl2.4H2O, HCl and NH4OH were used as raw materials to synthesize the MnFe2O4. The synthesis was carried out at various temperatures of 70, 100 and 130°C, respectively. The physical and the magnetic properties of the samples were analysed by using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Vibrating Sample Magnetometer (VSM). The diffraction pattern indicates that the MnFe2O4 is the dominant phase. The crystallite size tends to increase as the synthesis temperature increased while the saturation magnetization of MnFe2O4 tends to decrease.
