Research Abstract

In order to reveal the mechanism of metal - insulator transition of quasi-one-dimensional BaVS3 at 70 K, we have investigated the change of the V 3d state across the transition mainly by means of angle-resolved photoemission spectroscopy (ARPES) and soft x-ray absorption linear dichroism spectroscopy (LD). ARPES studies revealed that the a1g orbital forms a gap at 150 - 120 K, far above 70 K, due to one-dimensional instability, while the egp orbital forms a gap just at 70 K due to localization. LD studies, on the other hand, revealed that the occupancy ratio of the V 3d orbitals is unchanged across the transition. Theoretical analyses of the LD spectra highly suggest that the V 3d orbitals aligns with egp-egp-egp-a1g order along the V chain.
