Infrared study of spin-Peierls compound alpha'-NaV2O5
D. Smirnov, J. Leotin, P. Millet +2
Infrared reflectance of alpha'-NaV2O5 single crystals in the frequency range from 50 cm-1 to 10000 cm-1 was studied for a, b and c-polarisations. In addition to phonon modes identi…
X-ray Investigation of the Magneto-elastic Instability of alpha'-NaV2O5
S. Ravy, J. Jegoudez, A. Revcolevschi
We present an X-ray diffuse scattering study of the pretransitional structural fluctuations of the magneto-elastic transition in alpha'-NaV2O5. This transition is characterized by…
The symmetry problem in NaV2O5
A. Damascelli, D. van der Marel, J. Jegoudez +2
We discuss the symmetry of NaV2O5 in the high temperature phase on the basis of optical conductivity data. Conclusive information cannot be obtained by studying the optically allow…
Inversion symmetry in the spin-Peierls compound NaV2O5
A. Meetsma, J. L. de Boer, A. Damascelli +3
At room-temperature NaV2O5 was found to have the centrosymmetric space group Pmmn. This space group implies the presence of only one kind of V site in contrast with previous report…
Charged Magnons in NaV2O5
A. Damascelli, D. van der Marel, M. Grueninger +4
We investigated the temperature-dependent optical conductivity of NaV2O5 in the energy range 4 meV-4 eV. The intensities and the polarization dependence of the detected electronic…
