Abstract
A comprehensive global and local structural characterization using X-ray and neutron diffraction, and EXAFS have been performed to investigate the effect of electrical poling on the structure of (1−x)Na0.5Bi0.5TiO3–(x)K0.5Bi0.5TiO3 compositions. While the annealed samples showed definite indication of presence of local displacive disorders in all the compositions studied (0 < x < 0.3), this disorder persisted to some extent even after poling the samples. The tendency of electric field to reduce the local displacive disorder decreased with increasing K0.5Bi0.5TiO3 content in the samples.
