摘要：

Ce-doped BaTiO3 (BTO) films were grown by pulsed laser deposition. Highly c-axis-oriented BTO:Ce/YBa2Cu3O7-x bilayer structures on a SiTiO3 (100) substrate were fabricated for electrical property characterization. Typical hysteresis and butterfly type C-V plots were observed. The remanent polarization and coercive field are 3 mu C/cm(2) and 20 kV/cm, respectively. Highly a-axis-oriented Ce-doped and undoped BTO films were also deposited on MgO(100) substrates. Their linear and quadratic electro-optic effects were measured and compared. The Ce-doped films showed a larger linear electro-optic coefficient and obvious hysteresis in the quadratic electro-optic coefficient. (C) 1997 American Institute of Physics.
