We present results of numerical simulation of thermodynamics for array of Classical Heisenberg spins placed on 2D square lattice, which effectively represents the behaviour of single layer. Using Metropolis algorithm, we show the temperature behaviour of system with competing Heisenberg and Dzyaloshinskii-Moriya interaction (DMI) in contrast with classical Heisenberg system. We show the process of nucleating of skyrmion depending on the value of external magnetic field. We proposed the controlling method for movement of skyrmions.
