Large anomalous Hall effect in kagomé ferrimagnetic HoMn6Sn6 single crystal

•The magnetic and transport properties of HoMn6Sn6 single crystal have been investigated systematically in this work.•we present the quantitative results on the intrinsic and extrinsic mechanisms contributing to the anomalous Hall effect.•-−1The contribution of extrinsic mechanism cannot be neglected in the spin reorientation transition temperature range. 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 σxy,intA 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.
