Polycrystalline samples of mixed composites of Ni0.93Co0.02Mn0.05Fe2O4 + BaTiO3 were prepared by conventional double sintering ceramic method. The phase analysis was carried out by using X-ray diffraction technique. Variation of dc resistivity and thermo emf was studied as a function of temperature. AC conductivity (sigma(ac)) was investigated in the frequency range 100 Hz-1 MHz. The loss tangent (tan delta) measurements conclude that the conduction mechanism in these samples is due to small polaron hopping. The magnetoelectric conversion factor, i.e. dc(ME) (H) was studied as a function of intensity of magnetic field and the maximum value 407 mu V/cm/Oe was observed at a field of 0.8 kOe in a composite with 85% BaTiO3 and 15% Ni0.93Co0.02Mn0.05Fe2O4 phase.
