Anomalous electronic Raman scattering in Na_xCoO_2 H_2O
P. Lemmens, K. Y. Choi, V. Gnezdilov +5
Raman scattering experiments on Na_{x}CoO_2 yH_2O single crystals show a broad electronic continuum with a pronounced peak around 100 cm-1 and a cutoff at approximately 560 cm-1ove…

Spin gap formation in the quantum spin systems TiOX, X=Cl and Br
P. Lemmens, K. Y. Choi, R. Valenti +4
In the layered quantum spin systems TiOCl and TiOBr the magnetic susceptibility shows a very weak temperature dependence at high temperatures and transition-induced phenomena at lo…
