摘要：
Bi4LaFeTi3O15 films were deposited on (111) Pt/Ti/SiO2/Si using a sol-gel process. The films have a four-layered Aurivillius structure with random orientation, which were confirmed by x-ray reflectivity and grazing incidence x-ray diffraction. As expected, the films show room-temperature multiferroic properties with a remanent polarization P-r of similar to 17 mu C/cm(2) and a saturated magnetization M-s of similar to 1.4 emu/cm(3). More interestingly, a strong magneto-electric coupling was observed at room temperature with a converse magnetoelectric coefficient of 21% and a magneto-dielectric coefficient of 2%, resulting from the local Fe2+/Fe3+ charge ordering. Both x-ray photoelectron spectroscopy and temperature-dependent dielectric spectra provide evidence that the Fe2+ and Fe3+ coexist in Bi4LaFeTi3O15 films. (c) 2018 Elsevier B.V. All rights reserved.
