Краткий обзор статьи: We show that instantaneous configurations of 180 degree domain walls constructed on a square lattice in a two-dimensional and S=1/2 Ising-type model exhibit fractal structure. The fractal dimension depends on the coupling parameters and it is a continious function of the temperature. The wall thickness in the neighbourhood of Tc presents scaling properties in good agreement with the classical theory by Landau.
