Orbitally driven spin pairing in the three-dimensional nonmagnetic Mott insulator BaVS3: Evidence from single-crystal studies
Static electrical and magnetic properties of single crystal BaVS3 were measured over the structural (T-S=240 K), metal insulator (T-MI=69 K), and suspected orbital ordering (T-X=30 K) transitions. The resistivity is almost isotropic both in the metallic and insulating states. An anomaly in the magnetic anisotropy at Tx signals a phase transition to an ordered low-T state. The results are interpreted in terms of orbital ordering and spin pairing within the lowest crystal-field quasidoublet. The disordered insulator at T-X.
