Abstract

We have measured Raman spectra of barium vanadium sulfide (formula presented) single crystals in a broad temperature range (15 K-300 K). Three Raman active modes are found at about 193, 350, and (formula presented) The assignment of the observed modes of (formula presented) is carried out on the basis of the symmetry coordinate analysis. The mode at (formula presented) shows a dramatic intensity increase and a line asymmetry by lowering the temperature below 30 K. We believe that this behavior is connected with the orbital and spin ordering in this compound.
