Z-type hexagonal ferrite magnetoelectric coupling ceramic material and preparation method thereof
The invention discloses a Z-type hexagonal ferrite magnetoelectric coupling ceramic material and a preparation method thereof. Belongs to the field of magnetoelectric coupling materials. The invention aims to solve the problems that the existing multiferroic material has ferroelectricity, has few ferromagnetism types, and is low in magnetoelectric coupling strength and low in magnetoelectric coupling tolerance temperature. The chemical formula of the material is Ba < x > Sr < 3-x > Co < 1.25 > Cu < 0.75 > Fe < 24 > O < 41 >, wherein x is equal to 0 to 3; the material is prepared by adopting a staged sintering method in an oxygen atmosphere. The product provided by the invention has both ferroelectricity and ferromagnetism and also has strong magnetoelectric coupling performance. The product can realize the performance of magnetoelectric coupling induced under the condition of externally applying a small magnetic field, the dynamic magnetoelectric coupling performance of the product can be regulated and controlled by the change of the directions of a pre-polarized electric field and an externally-applied sweep field, and the performance of the dynamic magnetoelectric coupling performance under the room temperature condition is broken through under the condition of a certain Ba doping ratio. The method can be applied to the field of magnetoelectric coupling. The application range of the magnetoelectric material is enriched and widened, and the material has potential application advantages.
