  • Light scattering in LiCoPO₄ single crystal: analysis of the vibrational spectrum 
    Fomin, V.I.; Gnezdilov, V.P.; Kurnosov, V.S.; Peschanskii, A.V.; Eremenko, V.V.; Rivera, J.-P.; Gentil, S. (Физика низких температур, 1999)
    In a single crystal of LiCoPO₄ Raman scattering has been studied in a wide temperature range. Thirty-two of the 36 Raman-active vibrational modes predicted by group-theory analysis were detected. The experimental lines are ...
  • Light scattering on phonons in quasi-one-dimensional antiferromagnet CsFeCl₃·2H₂O induced by magnetic ordering 
    Kurnosov, V.S.; Pashkevich, Yu. G.; Peschanskii, A.V.; Fomin, V.I.; Yeremenko, A.V. (Физика низких температур, 2002)
    The appearance of new phonon lines in the Raman spectrum of the quasi-one-dimensional antiferromagnet CsFeCl₃·2H₂O as a consequence of magnetic ordering with a change of the unit cell volume was detected experimentally. ...
  • Phonon-assisted anti-Stokes excitation of the fluorescence of Mn²⁺ ions in the CsMnCl₃ ּ 2H₂O crystal 
    Eremenko, V.V.; Fomin, V.I.; Kurnosov, V.S. (Физика низких температур, 2000)
    We demonstrate that anti-Stokes excitation of Mn²⁺ ions in the CsMnCl₃⋅2H₂O crystal can occur through multiphonon addition to the energy of the photons of exciting light. The deficit dE between the energy of the Mn²⁺  ⁴T₁ ...
  • Raman scattering in LiNiPO₄ single crystal 
    Fomin, V.I.; Gnezdilov, V.P.; Kurnosov, V.S.; Peschanskii, A.V.; Yeremenko, A.V.; Schmid, H.; Rivera, J.-P.; Gentil, S. (Физика низких температур, 2002)
    The complete Raman spectra of a single crystal of LiNiPO₄ for a wide temperature range are reported. Among the 36 Raman-active modes predicted by group theory, 33 have been detected. The analysis of the spectra in terms ...
