High frequency dielectric and magnetic anomaly at the phase transition in NaV2O5
A. I. Smirnov, M. N. Popova, A. B. Sushkov +6
We found anomalies in the temperature dependence of the dielectric and the magnetic susceptibiliy of NaV_2O_5 in the microwave and far infrared frequency ranges. The anomalies occu…

Lattice vibrations of alpha'-NaV2O5
M. N. Popova, A. B. Sushkov, S. A. Golubchik +6
We have measured far infrared reflectance and transmittance spectra as well as Raman scattering spectra of α'-NaV2O5 single crystals for all the principal polarizations. The temper…

Folded modes in the infrared spectra of the spin-Peierls phase of CuGeO_3
M. N. Popova, A. B. Sushkov, S. A. Golubchik +2
Polarized far-infrared transmittance spectra of CuGeO_3 single crystals were measured at different temperatures (6K < T < 300K). Two spectral lines, at 284.2 cm-1 in E||c polarizat…
