Polarized absorption spectra of HoFe₃(BO₃)₄ single crystal in the range of 8500–24 500 cm−¹ were studied as a function of temperature beginning from 2 K. The ground and excited electron states of Ho³⁺ were identified. The abrupt changes of the spectra at the reorientation phase transition at 4.7 K w...
