Magnetic Raman scattering of the ordered tetrahedral spin-1/2 clusters in Cu_2Te_2O_5(Br_(1-x)Cl_x)_2 compounds
J. Jensen, P. Lemmens, C. Gros
Raman light-scattering experiments in the antiferromagnetic phase of the Cu_2Te_2O_5(Br_(1-x)Cl_x)_2 compounds are analyzed in terms of a dimerized spin model for the tetrahedral C…

Infrared optical properties of the spin-1/2 quantum magnet
G. Caimi, L. Degiorgi, N. N. Kovaleva +2
We report results on the electrodynamic response of , a low-dimensional spin-1/2 quantum magnet that shows a spin gap formation for T= 67 . The Fano-like shape o…
