FIG. 1.

Observed diffraction pattern from BNT-7BT at zero field (a), and selected region (b), both prior to electrical loading (black, top) and under a 3 kV/mm electric field at various angles to the electric field (red, bottom).

Image of FIG. 2.
FIG. 2.

Schematic of domain orientations in response to electric field. In (a), representative grain orientations are shown as a constant pseudocubic lattice parameter prior to electric-field application. In (b), the grain orientations are retained and the electric-field-induced tetragonal domain structure exhibits an orientation dependence of the lattice parameters and domain volume fractions.

Image of FIG. 3.
FIG. 3.

Lattice spacing of the tetragonal phase calculated from the positions of (002) and (200) type peaks (a). Domain texture (MRD) calculated from the intensities of (002) and (200) type peaks (b).
