Low Energy Singlets in the Excitation Spectrum of the Spin Tetrahedra System Cu_2Te_2O_5Br_2
P. Lemmens, K. Y. Choi, A. Ionescu +8
Low energy Raman scattering of the s=1/2 spin tetrahedra system Cu_2Te_2O_5Br_2 is dominated by an excitation at 18 cm^{-1} corresponding to an energy E_S=0.6Δ, with Δthe spin gap…

Evidence for an unconventional magnetic instability in the spin-tetrahedra system Cu_2Te_2O_5Br_2
P. Lemmens, K. -Y. Choi, E. E. Kaul +8
Thermodynamic experiments as well as Raman scattering have been used to study the magnetic instabilities in the spin-tetrahedra systems Cu_2Te_2O_5X_2, X=Cl and Br. While the phase…

Modeling the electronic behavior of -LiV2O5: a microscopic study
R. Valenti, T. Saha-Dasgupta, J. V. Alvarez +2
We determine the electronic structure of the one-dimensional spin-1/2 Heisenberg compound -LiVO, which has two inequivalent vanadium ions, V(1) and V(2), via density-fun…
