Highly anisotropic magnetism in the vanadium-based kagome metal TbV6Sn6
Abstract
RV6Sn6 (R=rare earth) compounds are appealing materials platforms for exploring the interplay between R-site magnetism and nontrivial band topology associated with the nonmagnetic vanadium-based kagome network. Here we present the synthesis and characterization of the kagome metal TbV6Sn6 via single-crystal x-ray diffraction, magnetization, transport, and heat capacity measurements. Magnetization measurements reveal strong, uniaxial magnetic anisotropy rooted in the alignment of Tb3 moments in the interplane direction below 4.3(2) K. TbV6Sn6 exhibits multiband transport behavior with high mobilities of charge carriers, and our measurements suggest TbV6Sn6 is a promising candidate for hosting Chern gaps driven via the interplay between Tb-site magnetic order and the band topology of the V-site kagome network.
