Аннотация: Infrared (IR) absorption spectra of HoFe3(BO3)(4) crystal have been obtained in spectral range 30-7000 cm(-1) at temperatures from 4 to 423 K. Vibrational frequencies have been simulated with 'Lady' software package both for high-temperature and low-temperature phases. The experimental spectra have been analyzed on the basis of calПоказать полностьюculated data, and interpreted within the framework of internal vibrations of ionic complexes of HoFe3(BO3)(4) crystal lattice. The spectral range under study was observed to have no Davydov splitting of internal vibrational modes due to unit cell multiplication. No effects of magnetic ordering on the IR spectra of the crystal under study were observed in the low-temperature range. (C) 2014 Elsevier B.V. All rights reserved.
