摘要：
Vortex-like inhomogeneities that can appear in ferromagnetic films with strong easy-plane uniaxial anisotropy in the presence of antidotes in the form of artificial nanoscale holes or nonmagnetic inclusions are investigated. Peculiarities of the structure of such type of nanoobjects are considered for various geometries of holes, and the effect of demagnetizing fields on vortex-like inhomogeneities localized near one, two, or four holes is analyzed. It is shown that the analytic estimates obtained here are in all cases in good agreement with the results of numerical simulation.
