Annotation The numerical approaches to the study of the magnetic states, properties, and phase transitions in the XY and Ising spin systems with the long-range exchange interaction is presented. The Monte Carlo calculations have been performed for a system of spins (superspins) on a square lattice with long-range RKKY interaction. It is shown that the Monte Carlo simulation systems RKKY interaction leads to the formation of a complex of the magnetic structure. We compared the results of simulation with experimental images of labyrinth domain structure of garnet ferrite films.
