Abstract:
In this work, the results of theoretical calculations of changing of forms of stripped domain borders in the presence of non-symmetrically localized cylindrical magnetic inhomogeneity shifted relatively its central axis are presented. Full changes of functional of magnetostatic energy mediated by curvature of domains borders are found. Analytical decisions for functions which determine curves of domain walls due to effect of non-symmetrically localized cylindrical magnetic inhomogeneity shifted relatively its central axis are obtained. In this work, the results of experimental observation of deformation of domain border in magnetic film at the presence of cylindrical magnetic domain shifted relatively central axis of stripped domain are also demonstrated. The comparison of theoretical and experimental values of size of maximal curve of magnetic stripped domain wall is carried on.
