Abstract

Sr_0.5Ba_0.5Nb₂O₆ (SBN50) thin films were prepared by the organic gel method. The microstructural variation of the gel powders and SEN thin films with annealing temperature was studied by differential thermal analysis (DTA), thermogravimetry (TG), Fourier transform infrared (FT-IR) and X-ray diffraction (XRD). The differences in the decomposition between Sr-Ba-Nb nitrate precursor solutions with different pH values were investigated. By annealing at 700°C for 2 h, polycrystalline SBN thin films with smooth and crack-free surface were derived from the precursor solution with pH=8. Electric properties measurement indicated that the SBN films demonstrated a ferroelectric hysteresis loop. The remanent polarization (P_r) and coercive field (E_c) were 8.17 μC/cm² and 16.9 kV/cm, respectively.
