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…
