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.

Physica A: Statistical Mechanics and its Applications
Recognized by the European Physical Society
Physica A publishes research in the field of statistical mechanics and its applications.
Statistical mechanics sets out to explain the behaviour of macroscopic systems by studying the statistical properties of their microscopic constituents.
Applications of the techniques of statistical mechanics are widespread, and include: applications to physical systems such as solids, liquids and gases; applications to chemical and biological systems (colloids, interfaces, complex fluids, polymers and biopolymers, cell physics); and other interdisciplinary applications to for instance biological, economical and sociological systems.
