Electrical, magnetic and magnetoelectric properties of 0.6BaTiO3–0.4BiFeO3/CoFe2O4 particulate composites

0.6BaTiO3–0.4BiFeO3/CoFe2O4 composites were synthesized by the conventional solid-state sintering method and the sintering temperature was 1100 °C. The electrical, magnetic and magnetoelectric properties were investigated. The results show that BaTiO3–BiFeO3 and CoFe2O4 phases can coexist in the composites and all the synthesized composites exhibit excellent electrical, magnetic and magnetoelectric properties. The magnetoelectric behaviors are strongly dependent on the concentration of CoFe2O4 and the dc magnetic field. The maximum magnetoelectric coefficient of the composites reaches up to about 8.47 mV/cm Oe.
