Abstract

We consider phase transitions in chiral magnets using the results of classical Monte Carlo calculations. As the model, we consider the spin-lattice Hamiltonian of a classical spin system, in which the exchange interaction between spin and the Dzyaloshinskii–Moriya interaction are taken into account. We analyze the behavior of the magnetic heat capacity, magnetic susceptibility, and the Bragg scattering intensity as functions of the model parameters. The results are compared with experimental data.
