Two ferrite ceramic materials, MgFe2O4 and MnFe2O4, were successfully   fabricated by a conventional sintering of nanosized powders (at 1373 K for 2   h) synthesized by soft mechanochemical route. The particle size and   morphology of powders were studied using X-ray diffraction (XRD) and   transmission electron microscopy (TEM). XRD analysis was carried out for the   determination of phase purity, crystal structure and average crystallite size   of sintered ferrites. Both mechanosynthesized ferrite samples show mean   crystallite sizes in the nm-range. Over the frequency range of 100 Hz to 1   MHz, impedance spectra of prepared ferrite ceramics are investigated at and   above room temperature. Changes in the impedance plane plots with temperature   have been discussed and correlated to the microstructure of materials. An   equivalent circuit model is applied to explore the electrical parameters   (resistance and capacitance) associated with grains and grain boundaries.   Complex impedance analysis indicates the dominance of grain boundary effects   which control the overall electrical behaviour of studied ferrites. The   decrease in grain boundary resistance with temperature suggests a thermally   activated conduction mechanism. [Projekat Ministarstva nauke Republike   Srbije, br. III43008 i br. III45003
