Iron Borate Based Crystals, Trigonal Weak Ferromagnets With Zero Orbital Moment: Synthesis and Modelling of Intracrystalline Interactions

The synthesis of mixed iron-gallium borates, Fe x Ga 1- x BO 3 , 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, {x} , are obtained at 0 K.
