Low energy excitations and dynamic Dzyaloshinskii-Moriya interaction in ${\alpha }^{\prime }$-NaV${}_2$O${}_5$ 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…
