“…In these TMDCs, the M x T S 2 (M = 3d transition metal, T = Ta, Nb) family [14] with x = 1/3 exhibit unique properties, due to the inserted ionic arranging in a stacked √ 3 × √ 3 su-perlattice, reducing the crystal symmetry. [15] For example, a chiral helical magnetic order was observed in Cr 1/3 NbS 2 , [5] a large anomalous Hall effect occurs in Co 1/3 NbS 2 . [16] In this article, on the basis of growing successfully high-quality V 1/3 TaS 2 crystals, we carried out the magnetization, longitudinal, and Hall resistivity measurements, combined with the electronic band structure calculations.…”

Intercalated transition metal dichalcogenides (TMDCs) attract much attention due to their rich properties and potential applications. In this Letter, we grew successfully high-quality V$_{1/3}$TaS$_{2}$ crystals by a vapor transport method. We measured the magnetization, longitudinal resistivity $\rho_{xx}$($T, H$), Hall resistivity $\rho_{xy}$($T, H$), as well as performed calculations of the electronic band structure. It was found that V$_{1/3}$TaS$_{2}$ is an A-type antiferromagnet with the Neel temperature $T_{N}$ = 6.20 K, and exhibits a negative magnetoresistance (MR) near $T_{N}$. Both band structure calculations and Hall resistivity measurements demonstrate it to be a magnetic semimetal.
