2. Effective Hamiltonian results evaluated in a BFO film, at 300 K and as a function of misfit strain; (a) tetragonality (c/a ratio) and (b) antiferrodistortive angles ω along the x-, y- and z-axes (ωX and ωY, red line and ωZ, blue line).

3. Measured (squares) remanent polarization versus strain and calculated components of the remanent polarization vector. D. Sando et al. Phil. Trans. R. Soc. A 2014;372:20120438 ©2014 by The Royal Society

4. Conversion electron Mössbauer spectra at 295 K for two BFO films; (a) one on GSO and (b) the other on PSO. The symbols correspond to the data, the red lines to a fit with a cycloidal model and the blue line to a fit with an antiferromagnetic (AF) order. D. Sando et al. Phil. Trans. R. Soc.
