摘要：

Domain walls in the commensurate phase of crystals which have a preceeding incommensurate phase are discussed on the basis of the Landau-type energy written in terms of two order parameters. The contribution from the Lifshitz invariant to the domain wall energy is analyzed, using the variation method. Contours representing two possible types of domain walls and spatial modulation of the order parameters in them are presented.
