Resumo

We studied the processes of formation and conditions of stability of skyrmion lattices during thermodynamic fluctuations in magnetoelectric films, namely, in a frustrated antiferromagnetic/ferroelectric bilayer on a triangular lattice. We calculate the ground state configurations with given parameters using the steepest descent method. We consider the thermodynamic fluctuations in influence of an external magnetic field on the ground state configurations and phase transitions occurring in the model using Monte Carlo simulation.
