X-ray anomalous scattering investigations on the charge order in -NaVO
S. Grenier, A. Toader, J. E. Lorenzo +8
Anomalous x-ray diffraction studies show that the charge ordering in -NaVO is of zig-zag type in all vanadium ladders. We have found that there are two models of…
Using electronic structure changes to map the H-T phase diagram of alpha'-NaV2O5
A. B. Sushkov, J. L. Musfeldt, S. A. Crooker +2
We report polarized optical reflectance studies of α'-NaV2O5 as a function of temperature (4-45 K) and magnetic field (0-60 T). Rung directed electronic structure changes, as measu…
Charge Ordering and Spin Dynamics in NaV2O5
B. Grenier, O. Cepas, L. P. Regnault +7
We report high-resolution neutron inelastic scattering experiments on the spin excitations of NaV2O5. Below Tc, two branches associated with distinct energy gaps are identified. Fr…
Optical spectroscopic study of the interplay of spin and charge in NaV2O5
A. Damascelli, C. Presura, D. van der Marel +2
We investigate the temperature dependent optical properties of NaV2O5, in the energy range 4meV-4eV. The symmetry of the system is discussed on the basis of infrared phonon spectra…
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…
