Abstract: In this paper, CoFe2O4/Cr2O3 nano-composites were prepared by sol gel auto-combustion route. The crystal structure of the as prepared composites was characterized by Rietveld refinement of X-ray diffraction pattern. The impedance spectrum reveals two types of relaxation in terms of two semicircles above 340K. The 1st semicircle is possibly due to the relaxation of grains whereas the 2nd semicircle corresponds to the grain boundary relaxation. The 1st relaxation shows non-Debye nature however the 2nd relaxation shows the Debye nature (extracted via HavriliakNegami model). The change in capacitance with the application of magnetic field gives an indication of magnetoelectric coupling in the prepared nano-composites.
