Resumo

Stability conditions are studied for vortex-like inhomogeneities in perforated ferromagnetic films with strong easy plane uniaxial anisotropy. It is shown that nontrivial magnetic structures characterized by the absence of out of plane magnetization can be observed at absolute values of the anisotropy constant exceeding a certain threshold value. Possible (analytical, numerical, and empirical) methods for calculating this threshold value are developed. Universal estimates of the minimum permissible value of the anisotropy constant are obtained in a number of important cases. Feasible scenarios for the loss of stability of the magnetic structure under the variation of the material parameters of the film are analyzed.
