The thermodynamic properties of the helical spins with a magnetoelectric coupling are studied theoretically using Monte Carlo simulations. It is shown that the spin?spin correlations are affected by thermal fluctuations and by an electric field. Results for the temperaturedependence of the ferroelectric polarization and for the electric susceptibility are presented and analyzed with a focus on the multiferroic phase transition.
