Intercalated transition metal dichalcogenides(TMDCs)attract much attention due to their rich properties and potential applications.In this article,we grew successfully high-quality V1/3TaS2 crystals by a vapor transport method.We measured the magnetization,longitudinal resistivity ρxx(T,H),Hall resistivity ρxy(T,H),as well as performed calculations of the electronic band structure.It was found that V1/3TaS2 is an A-type antiferromagnet with the Neel temperature TN=6.20 K,and exhibits a negative magnetoresistance(MR)near TN.Both band structure calculations and Hall resistivity measurements demonstrated it is a magnetic semimetal.
