摘要: We have found unique hierarchical domains in Na1/2Bi1/2TiO3 single crystals. A tetragonal ferroelastic domain structure is unchanged on cooling from 520 to 25 °C. Polar microdomains then nucleated the rhombohedral ferroelectric phase within geometrical restrictions imposed by inherited domains.
