摘　　要：We study the influence of Cr doping on magnetic properties ofα-RuCl3 single crystals in detail.With increasing Cr content,the c-axial lattice parameter increases gradually,implying that the Cr doping may weaken the interlayer interactions.The magnetism of Ru1-xCrxCl3 single crystals evolves from a long-range AFM order to a possible spin-glass state with Cr doping.The appearance of a possible spin-glass state can be explained by the introduction of FM interaction by Cr3+ions,which competes with the AFM interaction between Ru3+ions.Noreover,the larger magnetic moment of Cr3+ion with S=3/2 than Ru3+ion with Jeff=1/2 also results in a monotonic increase of the effective moment of Ru1-xCrxCl3 single crystal.
