Abstract:

In the absorption spectra of the hexagonal single-crystal manganite HoMnO3 in the paramagnetic ferroelectric state, lines near 1.1 and 2.0 mu m were observed associated with the transitions (5) I (8) -> (5) I (6) and (5) I (8) -> (5) I (7), respectively, within the 4f (10) configuration of the Ho3+ ion. At T = 80 K, to the (5) I (8) -> (5) I (7) transition corresponds one band at 1.9 mu m for both polarizations E ayen c and E aSyen c. As the temperature increases from 80 to 293 K, a low-energy band with a peak at 2.04 mu m for E aSyen c and a peak at 2.07 mu m for E ayen c arises associated with transitions from an excited Stark level of the ground (5) I (8) multiplet to the Stark levels of the (5) I (7) multiplet and with an increase in the population of the initial Stark level, the energy of which is similar to 100 K.
