Phonon and spin dynamics in BaVS3 single crystals
- We have measured Raman spectra of barium vanadium sulfide (BaVS3) single crystals in a broad temperature range (15 K–300 K). Three Raman active modes are found at about 193, 350, and 366cm−1. The assignment of the observed modes of BaVS3 is carried out on the basis of the symmetry coordinate analysis. The mode at 350cm−1 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.
