【 摘 要 】

Using high intensity powder neutron diffraction the magnetic structure of a-RuCl3has been determined. Following the magnetic propagation vector κ = (1/2, 0, 1/2) the Jeff= 1/2 spins of Ru3+adopt a Zigzag type arrangement on the honeycomb lattice of the layered P3112 structure. The magnetic moments are oriented perpendicular to the trigonal axis. Similarities and differences to previously published single crystal data are discussed. The low value of the magnetic moments, μRu= 0.5(1) μBindicates a possible closeness of α-RuCl3to the Kitaev spin liquid state.
