The resonant frequencies and damping parameters of eigen oscillations that are excited in two-dimensional lattice of magnetic nanoelemens were determined. The energy barriers between different states of magnetization of the nanoparticles were calculated. Dynamic characteristics for the processes of transition to a unsaturated state from saturated one for a single nanoparticle were defined. The microwave magnetic susceptibility of two-dimensional lattice Py- nanoparticles was measured. The features of nonlinear ferromagnetic resonance in a nanopatterned ferromagnetics was determined. The shape of the resonance curves for nonlinear ferromagnetic resonance regime was determined, and it was shown that this dependence is strongly determined by the nanostructure size.
