Domain wall solutions for EHM model of crystal

For a one-dimensional discrete model of a crystal the solution of the form of a moving domain wall in an odd-periodic commensurate structure was deriv ed in the continuum approximation. The energy of the commensurate odd-perio dic structure; the width and the energy of domain wall were expressed in te rms of the amplitudes of harmonics of carrying commensurate structure. With the use of the result by Ishibashi, the relation between domain wall solut ions in odd-periodic and even-periodic commensurate structures Tvas establi shed. The applicability and the accuracy of the solutions were also discuss ed. The obtained solutions were found to he more accurate and general than those by other authors.
