Enhanced anomalous Hall effect in kagome magnet YbMn 6 Sn 6 with intermediate-valence ytterbium

We report on the magnetization and anomalous Hall effect (AHE) in the high-quality single crystals of the kagome magnet YbMn 6 Sn 6 , where the spins of the Mn atoms in the kagome lattice order ferromagnetically and the intermediate-valence Yb atoms are nonmagnetic. The intrinsic mechanism plays a c...

Description
Summary:We report on the magnetization and anomalous Hall effect (AHE) in the high-quality single crystals of the kagome magnet YbMn 6 Sn 6 , where the spins of the Mn atoms in the kagome lattice order ferromagnetically and the intermediate-valence Yb atoms are nonmagnetic. The intrinsic mechanism plays a crucial role in the AHE, leading to an enhanced anomalous Hall conductivity (AHC) compared with the other rare-earth R Mn 6 Sn 6 compounds. Our band structure calculation reveals a strong hybridization between the 4f electrons of Yb and conduction electrons.
