Abstract

The behavior of the skyrmionic character of the square lattice with the Heisenberg model which contains exchange interaction and DMI between the nearest neighbor spins and external time-dependent periodic magnetic field is investigated by Monte Carlo simulation. The effect of the amplitude and period of the field on the skyrmionic character of the lattice was obtained. It is shown that, as in the magnetization of the lattice, the skyrmion number has a hysteretic character in one period of the field.
