摘要：
Linear orientational defects (2pi and pi walls) in freely suspended thin smectic C films exposed to a magnetic field were studied. The bend and splay elastic constants, as well as the orientational viscosity of a two-dimensional c-director field, were determined. It was established that a change in the polar and azimuthal angles of magnetic-field orientation in a sample cardinally transforms the wall structure. This is caused by the anisotropy of orientational elasticity of the c director. (C) 2003 MAIK "Nauka/Interperiodica".
