  title = {Strain-driven phase transitions and associated dielectric/piezoelectric anomalies in BiFeO3 thin films},
  abstract = {Strain-driven phase transitions and related intrinsic polarization, dielectric, and piezoelectric properties for single-domain films were studied for BiFeO3 using phenomenological Landau-Devonshire theory. A stable and mixed structure between tetragonal and rhombohedral-like (monoclinic) phases is predicted at a compressive misfit strain of um =-0.0382 without an energy barrier. For a tensile misfit strain of um =0.0272, another phase transition between the monoclinic and orthorhombic phases was predicted with sharply high dielectric and piezoelectric responses. © 2010 American Institute of Physics.},
