, and the results of modeling intracrystalline interactions, namely exchange, Dzyaloshinskii–Moriya, and dipole–dipole couplings in these crystals by means of the Monte Carlo technique using laboratory-developed codes are presented. The dipole–dipole contribution to basal magnetocrystalline anisotropy is calculated considering extended dipoles as Ampérian currents. The dependences of the intracrystalline interaction constants on iron contents,
