Abstract

We measured optical absorption and magnetic circular dichroism spectra of Na_0.4Ho_0.6F_2.2 single crystal in the region of ⁵I₈→ ⁵F₃, ⁵F₂ and ³K₈ transitions in Ho³⁺ ion at 90 K and room temperature. Paramagnetic magneto-optical activities (MOA) of the transitions were found for these two temperatures and compared with the theory based on the nature of f-f transitions allowance. It was shown that nature of allowance of three considered transitions is different. The MCD spectra were also analyzed in approximation of the |J,±M_J⟩ wave functions of the free atom and using concept of the crystal quantum number. Using this concept and experimental paramagnetic MOA, we found that M_Jeff = 2.1 for the initial state of the ⁵I₈→ ⁵F₃ transition.
