Ground State of the Quasi-1D \ resolved by Resonant Magnetic X-ray Scattering
Abstract
Resonant-magnetic x-ray scattering (RMXS) near the vanadium L2,3-absorption edges has been used to investigate the low temperature magnetic structure of high quality \ single crystals. Below TN = 31 K, the strong resonance revealed a triple-incommensurate magnetic ordering at wave vector (0.226 0.226 ) in the hexagonal notation, with = 0.033. The simulations of the experimental RMXS spectra with a time-dependent density functional theory indicate an antiferromagnetic order with the spins polarized along a in the monoclinic structure.
