Abstract

Nanocrystalline powder with particle size 50 nm and thin film with thickness 2 μm of SrBi₂Ta₂O₉ (SBT) were successfully prepared by the sol-gel method, using strontium acetate semihydrate [Sr(CH₃COO)₂·1/2H₂O] and bismth subnitrate [BiO(NO₃)], and tantalum ethoxide [Ta(OCH₂CH₃)₅] as source materials, glacial acetic and ethylene glycol as solvents. The XRD and TEM results indicated that SBT layer-perovskite phase powder obtained has to be single phase, Pt layer had a (100) predominate orientation, and the (115), (200) of SBT thin film formed after being annealed at 800 °C for 1 min. The typical hysteresis loop of SBT thin film on Pt/Ti/SiO₂/Si was obtained, and the measured Pr and Ps values of the SBT thin film were 5.5 and 8.8 μC/cm², respectively.
