Title: Electrical and thermal transport in van der Waals magnets 2 H M x TaS 2   ( M = Mn ,   Co )

Journal Article · · Physical Review Research

We report a detailed study of electrical and thermal transport properties in 2H-Mx TaS2 (M = Mn, Co) magnets where M atoms are intercalated in the van der Waals gap. The intercalation induces ferromagnetism (FM) with an easy-plane anisotropy in 2H-Mx TaS2, but FM with a strong uniaxial anisotropy in 2H-Co0.22TaS2, which finally evolves into a three-dimensional antiferromagnetism (AFM) in 2H-Co0.34TaS2. Temperature-dependent electrical resistivity shows metallic behavior for all samples. Thermopower is negative in the whole temperature range for 2H-CoxTaS2, whereas the sign changes from negative to positive with increasing Mn for 2H-Mnx TaS2. The diffusive thermoelectric response dominates in both high- and low-temperature ranges for all samples. A clear kink in electrical resistivity, a weak anomaly in thermal conductivity, as well as a slope change in thermopower were observed at the magnetic transitions for 2H-Mn0.28 TaS2(Tc ≈ 82 K) and 2H-Co0.34TaS2 (TN ≈ 36 K), respectively, albeit weaker for lower x crystals. Co-intercalation promoted FM to AFM transition is further confirmed by Hall resistivity; the sign change of the ordinary Hall coefficient indicates a multiband behavior in 2H-CoxTaS2.
