The submbicron-scaled magnetism of solid state is a rapidly developing research area with a promising applied potential. Nanomagnets are often considered as elements of fast nonvolatile memory devices of high density. Up to now the theoretical study in this direction was restricted mostly by planar structures. In the current research we propose an universal approach for describing the magnetization dynamics of an arbitrary curved magnetic film. We believe that the proposed method significantly expands facilities of the nanomagnetism area by introducing into the consideration a wide range of new objects: magnetic nanotubes, curvilinear nanowires, nanocaps of spherical and other geometries.
