Analysis of the intrinsic magnetic properties ofR2Fe17single crystals (R=Y,nDy,nHo,nEr)

Abstract
The magnetic behavior of some R2 Fe17 single crystals have been analyzed quantitatively in a wide temperature range, using a two-sublattice approximation for the magnetic structure and taking into account isotropic exchange and single-ion crystal-field interactions. The 3d sublattice behavior has been described phenomenologically, from the study of the experimental magnetization results in a Y2 Fe17 single crystal. The parameters A20, A40, A60, A66, describing the crystal-field interaction in the different R2 Fe17 compounds (R=Er,nDy,nHo) have been determined. The calculated magnetic behavior shows good agreement with experimental magnetization results in the temperature range 4.2 to 300 K, demonstrating the reliability of the determined parameters.
