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…
Magneto-optical Kerr effect in
G. Caimi, S. Broderick, H. R. Ott +3
We have measured the magneto-optical Kerr rotation of ferromagnetic with x=0.2 and 0.4, as well as of serving as the non-magnetic reference material…
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…
Optical evidence for a spin-filter effect in the charge transport of
A. Perucchi, G. Caimi, H. R. Ott +3
We have measured the optical reflectivity of as a function of temperature between 1.5 and 300 and in external magnetic fields up to 7 . The sl…
