Far-infrared signature of the superconducting gap in intercalated graphite CaC6
U. Nagel, D. Huvonen, E. Joon +3
Terahertz reflectance spectra of the Ca-intercalated graphite CaC6 reveal a superconducting gap below 11K. The gap signature lacks a sharp onset to full reflectivity at 2Delta, but…
Magneto-optic far-infrared study of SrCuO: triplet excitations in chains
D. Hüvonen, U. Nagel, T. Rõõm +4
Using far-infrared spectroscopy we have studied the magnetic field and temperature dependence of the spin gap modes in the chains of SrCuO. Two triplet modes T…
Far-infrared spectroscopy of spin excitations and Dzyaloshinskii-Moriya interactions in a Shastry-Sutherland compound SrCu(BO)$_2
T. Rõõm, D. Hüvonen, U. Nagel +2
We have studied spin excitation spectra in the Shastry-Sutherland model compound SrCu(BO) in magnetic fields using far-infrared Fourier spectroscopy. The transitions fr…
Low energy excitations and dynamic Dzyaloshinskii-Moriya interaction in -NaVO studied by far infrared spectroscopy
T. Rõõm, D. Hüvonen, U. Nagel +2
We have studied far infrared transmission spectra of alpha'-NaV2O5 between 3 and 200cm-1 in polarizations of incident light parallel to a, b, and c crystallographic axes in magneti…
