CoFe2O4/BaTiO3 layered magnetoelectric composite material and preparation method thereof
The invention discloses a CoFe2O4/BaTiO3 layered magnetoelectric composite material and a preparation method thereof. The preparation method comprises the following steps: sintering BaTiO3 powder and CoFe2O4 powder at the temperature of 1000 to 1050 DEG C in a 2-2 composite base superposition arrangement mode, thereby obtaining the CoFe2O4/BaTiO3 layered magnetoelectric composite material. With the adoption of the 2-2 composite base superposition arrangement mode, mutual reaction between two phases can be effectively inhibited so as to maintain the respective characteristics, so that the prepared composite material has high ferroelectricity and high ferromagnetic property. The electric constant reaches 1900-4500, and the dielectric loss is 0.19-1.50. The saturated polarization Ps is 14.8-18.7mu C/cm<2>, the coercive field Ec is 8.6-14.6kV/cm, and the saturation magnetization Ms is 3.4-20.9emu/g.
