Abstract

In this work (Cex Fe0.05Mg0.95-xO) nano particles (where x= 0, 0.025, 0.05, 0.075 and 0.10) were prepared by using sol-gel /auto combustion technique. The XRD results showed that all samples are polycrystalline in nature with cubic structure and lattice constant (a) decrease with increasing of Ce content in the sample. The crystallite size found an average size of (14.26 - 25.21 nm) was estimated by using Debye-Scherrer equation. The results of (SEM) showed that the morphology look like irregular aggregated of particles. The analysis of (EDX) confirmed the presence of Mg, Ce, Fe and O ions in the prepared samples. The results revealed that the dielectric loss factor and dielectric constant increase with increasing the content of Ceion, but the conductivity is inverse that behavior also the results showed that the initial magnetic permeability and relative loss factor were affected by change the content of Ce ion.
