Abstract
Recent experimental data for magnetostriction in the rare-earth (RE) ferroborates RFe3(BO3)4 with R=Pr and Tb are discussed from a theoretical point of view. Multipole moments of RE ions are calculated in the framework of a crystal-field model for the RE ion and the molecular-field approximation. Quadrupole approximation is shown to be sufficient for interpretation of data for longitudinal magnetostriction at the magnetic field along the trigonal axis. Parameters of PrFe3(BO3)4 are deduced when accounting for the experimental magnetization curves that manifest a spin–flop transition.
