N2 - Lead-free multiferroic magnetoelectric mixed and core shell composites of BaTiO3 and NiFe2O4 were synthesised by a two-step process. The structural, morphological, electrical, magnetic and dielectric properties of the as prepared samples were investigated in detail. XRD—Rietveld refinement (using JANA 2006 program) confirms the co-existence of two phases in the composite. The dielectric, ferroelectric and ferromagnetic properties of the systems was studied. The enhanced remanent polarization of core shell composite compared to pure BaTiO3 is the direct evidence of formation of core shell structure. The decrease in saturation values of composites can be attributed to the presence of nonmagnetic BaTiO3. The magnetoelectric coupling studies on BaTiO3@NiFe2O4 core–shell system exhibits enhancement due to the well-defined interface between the two phases. The sensitivity of electric properties to the applied magnetic field enables the systems for possible applications in magnetoelectric sensors.
