Beschreibungen/Notizen

• The S-walls (also called W'-walls) refer to those domain walls whose orientations do not coincide with crystallographic planes but rather change with temperature. A simple continuum model has been constructed to describe the S-wall structures that occur at a m 3 m → mmm ferroelastic phase transition. The model describes local values of the elastic strain components and the temperature dependence of the S-wall orientation. Distortions of unit cells across an S-wall was obtained numerically.
