Abstract

Optical absorption spectra of easy-plane antiferromagnet NdFe₃(BO₃)₄ in the region of the transition ⁴I_9/2 → ²H_11/2 of Nd³⁺ ion were studied in the temperature range 2–35 K and in external magnetic fields up to 65 kOe directed both along the C₃ axis and in the basal plane of the crystal. The splitting values of Nd³⁺ excited states in the exchange field of Fe³⁺ subsystem and g-factors of ²H_11/2 multiplet states were determined. Non-trivial dependences of splitting of some Nd³⁺ states on magnetic field point to the existence of anisotropic Fe–Nd exchange interaction for these excited states.
