Abstract
Kagome materials have been studied intensively in condensed matter physics. With rich properties, various Kagome materials emerge during this process. Here, we grew single crystals of Y 0.5 Fe 3 Sn 3 and confirmed an YCo 6 Ge 6 -type Kagome-lattice structure by detailed crystal structure characterizations. This compound bears an antiferromagnetic ordering at T N = 551 K, and shows a weak ferromagnetism at low temperatures, where an anomalous Hall effect was observed, suggesting the non-zero Berry curvature. With the unstable antiferromagnetic ground state, our systematic investigations make Y 0.5 Fe 3 Sn 3 a potential Kagome compound for Kagome or topological physics.
