摘要：

A microstructure causing the memory effect in the incommensurate phase of barium sodium niobate was investigated by means of a transmission electron microscope. A type of microdomain structure, which is constituted of a complicated array of microscopic ferroelastic domains with a modulation along the [100] direction, is found. Because this microdomain structure appears reversibly during the heating and cooling processes, the microdomain structure is directly related to the memory effect. © 1995 The American Physical Society.
