Abstract

The anomalous Hall effect (AHE) in ferromagnetic materials has attracted tremendous interests for their physical properties and great application in spintronics devices. Here, we report a large AHE in kagomé ferrimagnetic HoMn₆Sn₆ single crystal. The large intrinsic contribution of the anomalous Hall conductivity σ_xy,int^A was about 120 Ω⁻¹cm⁻¹, which was a considerable value compared to that in other materials with kagomé lattice. The anomalous Hall conductivity is significantly not affected by temperature, manifesting that large AHE is basically dominated by the intrinsic mechanism in connection with the Berry curvature. These results suggest that the HoMn₆Sn₆ alloy with Mn-based kagomé nets provides an excellent platform to comprehend the relationship between the magnetic structures and topological properties.
