Abstract

Three polycrystalline MgFe2O4 ferrite nanoparticles; MF1, MF2, and MF3 were prepared by the sol gel autocombustion method. The structural, elastic, and magnetic properties were studied using X-ray powder diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) measurements, and vibrating sample magnetometer (VSM). X-ray powder diffraction patterns confirm the formation of the pure cubic spinel phase. The particle size (D) was determined and found to be 3 nm, 37 nm, and 48 nm for MF1, MF2, and MF3, respectively. The elastic parameters showed a weak dependence on the particle size. The magnetic hysteresis loops indicated that the saturation magnetization (Ms) and coercivity (Hc) decreased with decreasing the particle size (D). The values of the coercivity are size dependence, which suggest that the prepared samples have a single magnetic domain structure. The temperature dependence of the magnetic parameters was investigated for the samples, whereas, the saturation magnetization and coercivity were increased with decreasing temperature.
