It was reported that both dielectricity and magnetism at room temperature were appreciably improved in Bi4Fe2TiO12 film compared with Bi4Fe2TiO12 bulk. X-ray diffraction profiles reveal similar crystalline nature and random orientation of the two, but X-ray photoelectron spectroscopy (XPS) experiments indicate that it is 1.4 eV lower binding energy of core-state O1s in the film relative to that of the bulk, so the improvement of multiferroics in the film is attributed to oxygen vacancies and high fraction of in-terface. The results have promising applications in multifunctional integrated devices.
