Abstract
The collective magnetization motion in an array of magnetostatically interacting ferromagnetic square elements is studied theoretically and experimentally. Dispersion laws are obtained for collective modes for some particular cases of the distribution of the topological charges πT of magnetic vortices in particles. Resonance curves are plotted with allowance for dissipation for various values of πT. An experimental investigation of the ferromagnetic resonance in a two-dimensional array of particles qualitatively supports the calculation results.
