摘要：
Ferroelectric memory was observed in {1-x SrBi2Ta2O9-x Bi3TiTaO9} material for the composition x = 0.3. Thus, there is interest in the investigation of detailed properties of this material system. We report on the structural and electrical properties of this material system using X-ray diffraction. Raman spectroscopy, impedance spectroscopy. and ferroelectric measurements. These studies suggest that high quality powder and thin films could be prepared for all compositions by a chemical solution route at the temperature ranging from 650 to 750 degreesC. Ferroelectric response was also observed in thin film (for x = 0.5) and pellet (for x = 0.0) samples. (C) 2001 Elsevier Science B.V. All rights reserved.
