A phenomenological theory of chiral symmetry breaking in magnetic nanostructures is developed considering induced, inhomogeneous chiral interactions (Dzyaloshinsky-Moriya-type). Application of the theory to films and multilayers with in-plane and out-of-plane magnetization predicts modulated and two-dimensional localized patterns (vortices). These new classes of magnetic patterns are intrinsically stable and localized on nanometer scale. Various experimental observations agree qualitatively with structures derived from this theory.
考虑到诱导的、非均匀的手性相互作用（Dzyaloshinsky-Moriya型），我们发展了一种关于磁性纳米结构中手性对称性破缺的唯象理论。将该理论应用于具有面内和面外磁化的薄膜和多层膜，预测了调制和二维局域模式（涡旋）。这些新型磁性模式本质上是稳定的，且在纳米尺度上局域化。各种实验观测结果在定性上与从该理论推导得到的结构相符。
