Abstract
A phenomenological theory of chiral symmetry breaking in magnetic nanostruc tures is developed considering induced, inhomogeneous chiral interactions ( Dzyaloshinsky-Moriya-type). Application of the theory to films and multilay ers with in-plane and out-of-plane magnetization predicts modulated and two -dimensional localized patterns (vortices). These new classes of magnetic p atterns are intrinsically stable and localized on nanometer scale. Various experimental observations agree qualitatively with structures derived from this theory.
