Abstract 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.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
