Effect of Na content and hydration on the excitation spectrum of the cobaltite Na_xCoO_2 yH_2O
P. Lemmens, V. Gnezdilov, N. N. Kovaleva +8
We report on a Raman scattering study on the superconducting cobaltite as function of Na content and hydration (x1/3, 3/4 and y0, 2/3, 4/3)…

Giant phonon anomalies in the pseudo-gap phase of TiOCl
P. Lemmens, K. Y. Choi, G. Caimi +4
We report infrared and Raman spectroscopy results of the spin-1/2 quantum magnet TiOCl. Giant anomalies are found in the temperature dependence of the phonon spectrum, which hint t…
