Study of Electrical and Magnetic Properties in Nano sized Ce-Gd Doped Magnesium Ferrite

摘要: crystalline magnesium Cerium Gadolinium ferrite with general formula M g Cex Gdy Fe2-x- y O4 (where x = 0.001, 0.012, 0.016, 0.018 and y=0.002) were prepared through sol- gel route from high purity nitrates of agnesium (M g), Cerium(Ce), Gadolinium(Gd) Iron. The samples sintered in microwave furnace then characterized by XRD, EDAX, FTIR SEM techniques. X-ray diffraction measurements confirmed the Nano size formation single phase cubic spinel structure ferrite. It was found that lattice constant decreases increase Gd 3+ Ce concentration lying range 53.24 - 53.78 nm, which monographs. studies show grain content. spectra shows two strong absorption bands within frequency 362.59-570.89 cm −1 . This concludes , occupies B-site. Saturation magnetization substituted ferrites is higher than unsubstituted VSM confirm magnetic behaviour used to understand electromagnetic properties these nano materials. permittivity decrease relative material.
