Abstract

Polarized absorption spectra of f-f absorption bands ⁴I_9/2 → ⁴(F_7/2 + S_3/2) and (⁴G_9/2 + ²K_13/2 + ⁴G_7/2) in the Nd³⁺ ion in the Nd_0.5Gd_0.5Fe₃(BO₃)₄ single crystal were studied as a function of temperature in the range of 2-40 K and as a function of magnetic field in the range of 0-65 kOe at 2 K. It was found out that the selection rules for f-f electron transitions substantially changed in the magnetically ordered state of the crystal, and they strongly depended on the orientation of the Fe and Nd ions magnetic moments relative to the light polarization. The splitting of the excited states of the Nd³⁺ ion in the exchange field of the Fe sublattice were determined. It was revealed that the value of the exchange splitting (the exchange interaction) did not correlate with the theoretical Landé factor. The Landé factors of the excited states were experimentally found. The local reorientation field induced metamagnetic transitions were observed in the excited states. In some excited states the energetically favorable orientation of the Nd³⁺ ion magnetic moment is opposite to that in the ground state.
