Abstract

The 50%CoFe2O4-50%BaTiO3 (in mass) composites with four different building structures, namely: CoFe2O4-BaTiO3 core-shell structure with CoFe2O4 in core, BaTiO3-CoFe2O4 core-shell structure with BaTiO3 in core, CoFe2O4-BaTiO3 mixed structure, and BaTiO3-CoFe2O4-BaTiO3 layer structure, have been synthesized and studied. The core-shell structures give higher magnetoelectric (ME) coefficients compared to the other structures. When using CoFe2O4 as core, the ME coefficient is highest, reaching 3.4 mV cm−1 Oe−1 for the sample pressed at 6 ton/cm2 and sintered at 1250°C for 12 h.
