The BTO/BYIG composites have been synthesized via the conventional solid-state sintering method and the sintering temperature was 1100 °C. The XRD patterns and the microstructures of the composites show that CH5183284 (Debio-1347) BaTiO3 and BiY2Fe5O12 phases can coexist in the composites. With increasing the concentration of BYIG, the P–E loops become more and more round due to the increasing leakage current. The resistivities of the composites decrease with increasing the concentration of BYIG. The saturation magnetization (Ms) of the composites increase with increasing the concentration of BYIG. The magnetoelectric behaviors are blending strongly dependent on the concentration of BYIG and the dc magnetic field. The maximum ME coefficient of the composite reaches up to about 0.21 mV/cm Oe.
