Ground State of the Quasi-1D Compound BaVS3 Resolved by Resonant Magnetic X-Ray Scattering

Résumé

Resonant magnetic x-ray scattering near the vanadium L2;3-absorption edges has been used to investigate the low temperature magnetic structure of high quality BaVS3 single crystals. Below TN ¼ 31 K, the strong resonance revealed a triple-incommensurate magnetic ordering at the wave vector ð0:226 0:226 %Þ in hexagonal notation, with % ¼ 0:033. The azimuthal-angle dependence of the scattering signal and time-dependent density functional theory simulations indicate an antiferromagnetic order within the ab plane with the spins polarized along a in the monoclinic structure.
