Abstract :
A sodium nitrite NaNO2 crystal is usually composed of 180° domains. These antiparallel ferroelectric domains are of (100) twin structure. The (121) twin structure which is well-known as the other twin is produced by the mechanical stress. Recently, it has been reported that (011) twin structure is produced by an application of a high ac electric field. The (011) twin in the matrix crystal is a rod shape region elongated to a-direction with a wedge type tip. The wall of the tip is moved by an additional application of an ac electric field and the rod grows toward the a-direction. The (011) twin is regarded as the ferroelectric 90°-domain of NaNO2. The growth of this new domain is reported in this paper
