SrBi<sub>2</sub>Ta<sub>2</sub>O<sub>9</sub> (SBT) films with thickness of about 200 nm were prepared on Pt/Ta/SiO<sub>2</sub>/Si substrates by metal-organic decomposition (MOD) method. A high electric field (250 kV/cm) was applied to SBT film during 750degC furnace annealing in atmosphere for 40 min. This applied electric field does some impacts on the(More)
