Abstract
The domain structures and their dynamics of BaTiO3 single crystals under in-situ electric fields along the 〈101〉 direction were investigated by using synchrotron radiation single-crystal X-ray diffractions. Diffraction patterns clearly show the presence of a 90° domain structure in 〈101〉-poled crystals. The linear characteristics of the strain and the polarization with respect to unipolar electric fields along the 〈101〉 direction suggest that the 90° domain structures established by poling treatments are not changed by applying electric fields. The diffraction analysis, however, provides direct evidence for a reversible change in the volume fractions of two kinds of 90° domains under unipolar in-situ electric fields.
