Abstract: The comprehensive understanding of (Na0.5Bi0.5)TiO3-BaTiO3 (NBT-BT) lattice structure is highly desired to develop lead-free ferroelectric materials. However, most of the previous studies focused on the improvement of piezoelectric properties at room temperature, and many structural… read more here.

DOI: 10.1063/5.0008522
Abstract: We have studied a dense domain structure (DDS) appearing during polarization reversal in rhombohedral (111)-cut lead magnesium niobate-lead titanate single crystals. The complicated shape of the switching current was explained by means of non-uniform motion… read more here.

DOI: 10.1103/physrevlett.124.037801
Abstract: Ferroelectric ordering in liquids is a fundamental question of physics. Here, we show that ferroelectric ordering of the molecules causes the formation of recently reported splay nematic liquid-crystalline phase. As shown by dielectric spectroscopy, the… read more here.
