SrTiO3-based high-frequency layered magnetoelectric composite material and preparation method thereof
The invention discloses a SrTiO3-based high-frequency layered magnetoelectric composite material and a preparation method thereof. The preparation method comprises the following steps: granulating SrTiO3 powder and Ni0.8Zn0.2Fe2O4 powder, pressing and molding the powder in a mold according to a 2-2 composite base superposition arrangement mode, discharging a PVA adhesive, sintering at the temperature of 1250 to 1300 DEG C, thereby obtaining the SrTiO3-based high-frequency layered magnetoelectric composite material. Because the SrTiO3 powder and Ni0.8Zn0.2Fe2O4 powder is molded according to the 2-2 composite base superposition arrangement mode, a ferroelectric phase and a ferrimagnetic phase are cofired together in a layered compounding mode, and the mutual reaction between the two phases can be effectively inhibited so as to remain the respective characteristics. Therefore, the composite material has excellent dielectricity and ferromagnetic property.
