摘要测量结果表明，Na0.5Bi0.5TiO3单晶中介电常数的长期变化与极性区存在有关。极地的大小和动态随温度的变化而变化。这些区域在外加电场中可以有序排列。
Abstract Performed measurements showed that in Na0.5Bi0.5TiO3 single crystals the long-time variation of the electric permittivity is connected with the existence of polar regions. The size and dynamics of the polar regions change with temperature. These regions may be ordered in an external electric field.
