Ca(Zn1/3Nb2/3)O3-based high-frequency layered magnetoelectric composite material and preparation method thereof
The invention discloses a Ca(Zn1/3Nb2/3)O3-based high-frequency layered magnetoelectric composite material and a preparation method thereof. The preparation method comprises the following steps: granulating Ca(Zn1/3Nb2/3)O3 powder and Ni0.8Zn0.2Fe2O4 powder, and pressing and molding the powder in a mold according to a 2-2 composite layered superposition arrangement mode; and discharging a PVA adhesive, and sintering at the temperature of 1250-1300 DEG C, thereby obtaining the Ca(Zn1/3Nb2/3)O3-based high-frequency layered magnetoelectric composite material. Because the Ca(Zn1/3Nb2/3)O3 powder and Ni0.8Zn0.2Fe2O4 powder can be arranged according to the 2-2 composite layered superposition arrangement mode, and a ferroelectric phase and a ferromagnetic phase are co-fired together by virtue of a layered compounding mode, mutual reaction between the two phases can be effectively inhibited, and the respective characteristics are maintained. Therefore, the composite material has high dielectric properties and also has good ferromagnetic properties.
