| titleOfInvention | Bi1-xRExFe1-yTMyO3/CoFe2O4 multiferroic composite film and preparation method thereof |
| abstract | The invention provides a Bi1-xRExFe1-yTMyO3/CoFe2O4 multiferroic composite film and a preparation method thereof. The composite film comprises a Bi1-xRExFe1-yTMyO3 crystalline film and a CoFe2O4 crystalline film which are compounded together. The preparation comprises the following steps: firstly preparing Bi1-xRExFe1-yTMyO3 precursor solution and CoFe2O4 precursor solution respectively; then spin-coating to prepare a plurality of layers of CoFe2O4 films on a substrate; next preparing a plurality of layers of Bi1-xRExFe1-yTMyO3 films on the CoFe2O4 films through spin coating to obtain a target product. The equipment requirement is simple, the prepared film is good in uniformity, chemical components are accurate and controllable, the doping content is easy to control, and the ferroelectric property and the ferromagnetic property of the film are greatly improved, and the film has high residual polarization value and residual magnetization value. |
