Essay

Dynamical regimes of the vortex polarity under the action of monochromatic magnetic field axis are found. Theoretical models for regular and chaotic polarity dynamics are proposed. Magnetization distribution in the vicinity of the Bloch point in the ferromagnetic nanosphere is found. Structure of the Bloch line and its switching mechanism in the sample with surface anisotropy are determined. Diagram of stationary magnetization states in the ferromagnetic Moebius ring with easy-normal anisotropy is calculated.
