Abstract

Optical absorption spectra of easy-plane antiferromagnet NdFe3(BO3)4 in the region of the transition 4I9/22H11/2 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 2H11/2 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.
