Abstract

The aim of this study is to synthesize, characterize, and finally, electrical property measurement of the nano-particles of polycrystalline magnesium and iron ferrite doped with rare earth (RE) materials cerium and erbium (MgCexEryFe2-x-yO4) with a series x = 0.4, 0.6, 0.8 and y = 0.6, 0.4, 0.2 systematically to understand the electro-transport behavior. These series are prepared by using the sol–gel auto combustion method maintaining the pH of the solution at 7, i.e., in neutral condition in order to maintain the desired dielectric material properties. These grown materials were made into pellets by applying minimum hydrostatic pressure and then silver coated for electric measurements. The dielectric behavior of the desired series is studied with varying frequencies from 100 Hz to 120 MHz, and the results obtained are discussed in terms of the resistance, admittance, susceptance, dielectric constant, dielectric loss, and tangent loss using an impedance analyzer. The variation behaviors with respect to frequency are discussed systematically in an exhaustive manner, and the studies indicate that these materials may have possible incorporation to fabricate microwave antennas to reduce energy losses and eventual applications.
