Perovskite (1-x)BiFeO₃–xPbTiO₃ thin films have been synthesized by the chemical solution deposition of metalorganic compounds. Homogeneous and stable BiFeO₃–PbTiO₃ precursor solutions were prepared by selecting appropriate starting materials and 2-methoxyethanol as a solvent. Perovskite BiFeO₃–PbTiO₃ powder samples with a composition ranging from x=0.1 to 0.5 showed weak ferromagnetism at room temperature. Perovskite BiFeO₃–PbTiO₃ single-phase thin films on Pt/TiO_x/SiO₂/Si substrates with good surface morphology were also fabricated by optimizing the PbTiO₃ content. Ferroelectric polarization–electric field (P–E) hysteresis loops were observed for 0.7BiFeO₃–0.3PbTiO₃ thin films, although some leakage current components are included at room temperature. The electrical resistivity of the BiFeO₃–PbTiO₃ films was improved in the low temperature region, and the remnant polarization and coercive field of the 700 °C-prepared 0.7BiFeO₃–0.3PbTiO₃ thin films at -190 °C were approximately 50 µC/cm² and 150 kV/cm, respectively. Furthermore, Mn doping into BiFeO₃–PbTiO₃ was effective in improving the ferroelectric properties of the resultant thin films at room temperature.
