Charge ordering signatures in the optical properties of beta-Na0.33V2O5
C. Presura, M. Popinciuc, P. H. M. van Loosdrecht +4
Temperature dependent optical spectra are reported for beta-Na0.33V2O5. The sodium ordering transition at T_Na = 240 K, and in particular the charge ordering transition at T_MI = 1…

Orbital Dimerization and Dynamic Jahn-Teller Effect in NaTiSiO
M. J. Konstantinović, J. van den Brink, Z. V. Popović +3
We study with the Raman scattering technique two types of phase transitions in the pyroxene compounds NaMSiO (with M=Ti, V, and Cr). In the quasi one-dimensional S=1/2 syst…
