Collective modes of the system of particles in the vortical states are analysed. Definition of experimental data and numerical simulations is done for excitations of high-frequency modes of magnetic nanostructures at the vortical and quasi-homogeneous states of separated nanounit in consideration of strong magnetic vortices interaction in terms of non-newtonian equation for vortex coordinate. The new types of the vortex states of small magnetic particles are described. A phase diagram is built and the theory of dynamical properties of magnetic particles arrays with an arbitrary anisotropy is developed. ---------------------------------------------------------------------- Product Description popup.authors Іванов Б.О.
