Magnetoelectric properties of CoFe2O4-BaTiO3 core-shell structure composite

The CoFe2O4-BaTiO3 core-shell structure composite has been successfully synthesized by wet chemical method. X-ray characterization showed that I he composite consisted of two single phases: CoFe2O4 and BaTiO3. The saturation magnetization of the CoFe2O4 component in comp)site was found to be similar to those of the bulk sample. It was observed that the longitudinal and transverse magnetoelectric coefficients of the core-shell structure are 18 times higher than those of the mixed structure.
