The structural and dielectric properties of cerium-chromium substitution in magnesium ferrite (x = 0, 0.1, 0.3, 0.5) prepared by spontaneous combustion of citric acid and calcined at a temperature of (1000 °C) were studied. The compositional characterization of the samples was carried out using XRD, FTIR, TEM, and the dielectric properties were measured using LCR. X-ray diffraction revealed the composition of the cubic spinel. The crystal size of magnesium ferrite was within (18-31 nm) and the lattice constant (8.327-8.393 Å). It was observed that the FTIR spectra of the compound MgCr0.5 – xCexFe1.5O4 remained in the spinel phase with a change in the concentration of Ce3+.Electron microscopy measurements showed that there are different lattice tips with potential d-spacing for Cr2O3, CeO2 and (-Fe2O3 phases. The d-spacing value of the most prominent ring in the (311) crystal planes of MgFe2O4 was close to its value in X-ray diffraction. It was found that the dielectric constant and the dielectric loss coefficient decreased with the increment in the frequency of the applied electric field and the alternating conductivity. |
