The film shows a two-domain stripe pattern, with the polarization vectors oriented along two 〈111〉 axes which form an angle of 71°. Polarization switching was investigated by locally poling the film. By combining the perpendicular and in-plane piezoresponse data we found that polarization rotates by 71° and 109°, while 180° switching is mainly observed at low fields. © 2005 American Institute of Physics.
