Abstract
- Multiferroic BiFeO 3 /Bi 4 Ti 3 O 12 bilayer films were prepared using chemical solution deposition. Well-defined interfaces between BiFeO 3 and Bi 4 Ti 3 O 12 layers and clear domain structures were observed. The ferroelectric, leakage, dielectric, piezoelectric, magnetic as well as magnetoelectric properties were investigated for the composite films. It is shown that the composite films not only exhibit ferromagnetic and ferroelectric properties, but also possess strong magnetoelectric effect at room temperature. Thus outstanding magnetoelectric properties are attributed to the excellent coupling effect between BiFeO 3 and Bi 4 Ti 3 O 12 layers, which leads to a strong coupling interaction between ferromagnetic and ferroelectric orders. The present work provides a feasible way of preparing magnetoelectric composite films and facilitating their applications in micro-electro-mechanical system and information storage devices.
