Synthesis and Characterization of the Kagome metal LuMn<sub>6</sub>Sn<sub>6</sub>

ORAL

Abstract

Kagome metals have attracted interest as they can host both non-trivial band topologies and flat bands, leading to the interplay of topology, magnetism, and strong correlations [1]. Recent studies of YMn6Sn6 have shown that it has multiple non-trivial magnetic phases, and that one of them hosts a large topological Hall effect near room temperature [2]. Here we report the crystal growth, magnetization, and electrical transport properties of a related compound, LuMn6Sn6. LuMn6Sn6 is an antiferromagnet with Néel temperature of 400 K. Magnetization and resonant ultrasound spectroscopy indicate a spin reorientation at 258 K. LuMn6Sn6 also displays an anomalous Hall effect when temperature is under 250K.
