Abstract: Multiferroic BaTiO3/CoFe2O4 superlattice films are deposited by laser molecular beam epitaxy. The film growth modes are studied by in situ reflection high energy electron diffraction and the film structures are revealed by high resolution transmission electron microscopy study. Ferroelectric switching behavior was studied by piezoresponse force microscopy, and it shows that good ferroelectricity was retained in the superlattice. Such a multiferroic superlattice also shows a magnetic exchange coupling under room temperature. Detailed analysis reveals that different growth modes and the substrate strain effect may be responsible for the magnetic exchange coupling.
