Layered magnetoelectric composite material and preparation method thereof
The invention discloses a layered magnetoelectric composite material and a preparation method thereof. The preparation method comprises the following steps: granulating 0.65BaTiO3-0.35(Na0.5Bi0.5)TiO3 powder and BiY2Fe5O12 powder respectively, then carrying out compression moulding in a mould in a manner of 2-2 composite barrier layer superposition arrangement, then removing a PVA adhesive, and sintering at 1100-1150 DEG C to obtain the layered magnetoelectric composite material. According to the layered magnetoelectric composite material and the preparation method thereof disclosed by the invention, because the 0.65BaTiO3-0.35(Na0.5Bi0.5)TiO3 powder and the BiY2Fe5O12 powder are moulded in the manner of 2-2 composite barrier layer superposition arrangement to co-sinter a ferroelectric phase and a ferromagnetic phase in a layered composite manner, inter-reaction between the two phases can be effectively suppressed, thus keeping the respective characteristics, and enabling the layered magnetoelectric composite material to be good in both ferroelectricity and ferromagnetism.
