- Abstract
Polycrystalline BiLaFeCoTiO (BLFCTO) thin films were prepared on (111)Pt/Ti/SiO/Si via a sol-gel process. The films have a single-phase four-layered Aurivillius structure with space group Fmm2. As expected, the BLFCTO films present room-temperature multiferroic properties with a remanent polarization 2 P of ~42 μC cm and a saturated magnetization M of ~7.2 emu cm. More interestingly, both dielectric relaxation behavior and room-temperature magneto-dielectric effect were observed in the BLFCTO films, probably resulting from the charge ordering of Fe and Fe. The magneto-dielectric coefficient of ~3.8% was obtained at room temperature under a low magnetic field of 0.5 T.
