Magneto-Electric Properties of 0.5Zn0.5Co0.5Fe2O4-0.5BaTiO3 Composite Powder

Magnetoelectric (ME) composite 0.5Co0.5Zn0.5Fe2O4-0.5BaTiO3 (CZFO-BTO) was synthesized by hybrid technique named as wet chemical-solid state technique. X- ray diffraction patterns revealed phase purity of constitutient phases and confirmed the manifestation of both CZFO and BTO with the ME composite structure. The structural phase transitions (rhombohedral-orthorhombic-tetragonal-cubic) of ME composite were observed in dielectric studies. We also observed saturated ferroelectric and magnetic properties. In addition, we are also reporting the transverse and longitudinal components of the magnetoelectric coefficient, which can be attributed to the direct strain mediated coupling between magnetostrictive nanoferrite (Co0.5Zn0.5Fe2O4) and piezoelectric BaTiO3 grains.
