Abstract

The observation of ordered domains and boundaries in Ba(Cd _1/3Ta _2/3)O ₃ perovskite dielectrics by electron microscopy was presented. It was shown that the individual nanoscale domains were found to be well ordered with hexagonal symmetry. It was observed that the electron diffraction revealed a twinned crystallographic relationship between domains. The conservative twin boundaries along the (001) and (110) planes and nonconservative antiphase boundaries with a projected displacement vector of the type [001] were also observed. The relationship between the energy and structure of the domain boundaries was described.
