The ground ytterbium doublet in h-YbMnO3 and the related low-temperature peculiarities of the compound
S. A. Klimin, N. D. Molchanova, N. N. Kuzmin +3
We have performed detailed temperature-dependent study of optical f-f transitions of the Yb3+ ions in h-YbMnO3 by means of Fourier-transform spectroscopy. The splitting of the grou…
Infrared study of lattice dynamics and spin-phonon and electron-phonon interactions in multiferroic TbFe3(BO3)4 and GdFe3(BO3)4
S. A. Klimin, A. B. Kuzmenko, M. A. Kashchenko +1
We present a comparative far-infrared reflection spectroscopy study of phonons, phase transitions, spin-phonon and electron-phonon interactions in isostructural multiferroic iron b…
Lattice vibrations of alpha'-NaV_2O_5 in the low-temperature phase. Magnetic bound states?
M. N. Popova, A. B. Sushkov, S. A. Klimin +4
We report high resolution polarized infrared studies of the quarter-filled spin ladder compound alpha'-NaV_2O_5 as a function of temperature (5K <= T <= 300K). Numerous new modes w…
