Abstract :
In this study, we investigated the solid solution of BiFeO3-PbTiO3 (BF-PT) system to improve the structural stability of perovskite phase and to enhance of several properties by using a morphotropic phase boundary (MPB) composition. Perovskite BF-PT single phase thin films were successfully fabricated though the formation of solid solution with PbTiO3. Although the electrical resistivity of BF-PT thin films was not sufficiently high at around room temperature, the large ferroelectricity was observed at low temperatures. The 0.7BiFeO3-0.3PbTiO3 thin films exhibited the Pr value of 60 muC/cm2 at -190degC.
