Single-phase oxide multiferroic ceramic with exchange bias effect and preparation method thereof
The invention provides a single-phase oxide multiferroic ceramic with exchange bias effect. The single-phase oxide multiferroic ceramic is as shown in the formula (I): Bi10Fe5.9Co0.1Ti3O30 (I). The single-phase oxide multiferroic ceramic has high Curie temperature, has ferroelectricity and ferromagnetism under the room temperature at the same time, and has intrinsic exchange bias effect. Not only a magnetic field can be regulated and controlled, but also an electric field can be regulated and controlled, the possibility of encoding storage information through the adoption of electric polarization and magnetic polarization at the same is provided, and then a magneto-electric mutual-control nonvolatile storage magnetic medium with ultrahigh storage density becomes possible.
