Phonons and Magnetic Excitations in Mott-Insulator LaTiO
M. N. Iliev, A. P. Litvinchuk, M. V. Abrashev +4
The polarized Raman spectra of stoichiometric LaTiO (T K) were measured between 6 and 300 K. In contrast to earlier report on half-metallic LaTiO, neither st…
Raman and Infrared-Active Phonons in Hexagonal HoMnO Single Crystals: Magnetic Ordering Effects
A. P. Litvinchuk, M. N. Iliev, V. N. Popov +1
Polarized Raman scattering and infrared reflection spectra of hexagonal HoMnO single crystals in the temperature range 10-300 K are reported. Group-theoretical analysis is perf…
Temperature-Dependent Polarized Raman Spectra of CaFe2O4
N. Kolev, M. N. Iliev, V. N. Popov +1
The Raman spectra of CaFe2O4 were measured with several exact scattering configurations between 20 and 520K and the symmetry of all observed Raman lines was determined. The Ag and…
Raman Phonons and Ageing-Related Surface Disorder in NaxCoO2
M. N. Iliev, A. P. Litvinchuk, R. L. Meng +3
The polarized Raman spectra from ab and ac surfaces of single crystal NaxCoO2 (x~0.7), parent compound of recently discovered superconductor NaxCoO2.yH2O, are reported and discusse…
