Abstract:
57 Fe-enriched BiFeO 3 (BFO) thin films were produced from a stoichiometric precursor solution by chemical solution deposition process. The perovskite BFO thin film fabricated at 550 °C on a Pt/Ti/SiO 2 /Si substrate showed saturated polarization–electric field ( P – E ) hysteresis loops. The remanent polarization P r and the coercive field E c at room temperature were 89 µC/cm 2 and 365 kV/cm, respectively. The Mössbauer spectra consisted of the antiferromagnetic perovskite BFO and a paramagnetic component at a fraction in the range of 11 to 14%. The secondary component was supposed to be due to Bi 2 Fe 4 O 9 and/or an amorphous component, influencing the ferroelectric property at room temperature. The Bi 2 Fe 4 O 9 thin film was also fabricated at 700 °C on a SiO 2 /Si substrate. Furthermore, we tried to measure the mapping images corresponding to the perovskite BFO and Bi 2 Fe 4 O 9 components separately using a Mössbauer spectroscopic microscope. A mapping image showed the distribution of the perovskite BFO component on the film.
