In this paper properties of magnesium doped copper ferrite are evaluated and it is often that suitable for microwave absorption application. Soft MgxCu1-xFe2O4 ferrite nanoparticles were synthesized by using simple chemical co-precipitation technique at 900C. The structural details and characterization is portrayed by utilizing powder XRD, FTIR, HRTEM, EPR and VSM procedures. XRD examples affirmed the single-stage cubic spinel structure of nanoparticles with no additional stage and crystalline size lies in the range 8-20 nm. It was observed that the lattice parameter diminishes with expanding cation substitution of Mg2+. EPR spectra of the considerable number of tests show a ferromagnetic single broad resonance signal shifts to the higher field on increasing Mg ions concentration.

Keywords: Lattice parameter; co-precipitation; maximum magnetization; dielectric constant.
