(Color online) First full hysteresis loop of the single crystal of at room temperature. The remnant polarization is and the coercive field is . The inferred full saturation polarization along the direction is close to . (Insert) Raw data.

FIG. 2.

(Color online) Gradual modification of the shape of the loops during electric field cycling. The loops lose their squareness and the quantities most affected are the coercive and saturation fields as well as the remnant polarization.

Image of FIG. 3.
FIG. 3.

(Color online) Decrease of the spontaneous polarization as well as the increase of the coercive field during electric field cycling as a consequence of a gradual increase of leakage current.
