Abstract
We report unusually high ferroelectric polarization in chemical solution processed thin films of BiFeO3–PbTiO3 (BF–xPT) of compositions near the morphotropic phase boundary (MPB). Saturated hysteresis loops were obtained showing a large remnant polarization of 80 μC/cm2 in thin films of composition BF–0.25PT with polarization decreasing for BF–0.30PT and BF–0.35PT. Structural analysis revealed single phase region with monoclinic Cm space group for composition x=0.25 while a two phase region of monoclinic (Cm) and tetragonal (P4mm) phase exists at x=0.30–0.35. The large polarization in BF–0.25PT films is attributed to superior polarizability of the monoclinic Cm phase.
