Shapes of moving 180°-wall affected by stresses due to a dislocation were obtained for TGS crystals from calculations based on Nakamura’s theory of domain growth. Anisotropic sidewise velocity, v, of wall motion under the stress T was determined on the assumption that v depended on T through the wall energy density σ; the T dependence of σ was derived from the Zhirnov-type continuum theory. An edge component, rather than a screw component, of a dislocation which is parallel to the ferroelectric axis affects the value of σ. Under a low field the wall is caught in the dislocation, while under a high field it easily passes through the dislocation. The results are in qualitative agreement with experimental observations.
