were studied by dielectric spectroscopy, polarized light microscopy (PLM) and piezoresponse force microscopy (PFM). Remarkable differences between heating and cooling run in permittivity vs. T curve and domain structures for poled specimen were found. The change in domain structures with poling from rhombohedral spindle-like domains with a few µm width to orthorhombic domains of ∼ 20µm width with rectangular cells in size of a few µm, characterized with antiferroelectic double hysteresis loop in electric field-induced strain behavior was found.
