Abstract
We report magnetic and electrical properties for single crystals of $\mathrm{Nd}{\mathrm{Mn}}_{6}{\mathrm{Sn}}_{6}$ and $\mathrm{Sm}{\mathrm{Mn}}_{6}{\mathrm{Sn}}_{6}$. They crystallize into a structure that has distorted, Mn-based kagome lattices, compared to the pristine kagome lattices in heavy rare-earth-bearing $\mathrm{R}{\mathrm{Mn}}_{6}{\mathrm{Sn}}_{6}$ compounds. They are high-temperature ferromagnets of which the R moment is parallel with the Mn moment. We observed a large intrinsic anomalous Hall effect (AHE) that is comparable to the ferrimagnetic, heavy-R siblings in a wide range of temperature. We conclude that their intrinsic AHE is stemming from the Mn-based kagome lattice, just as in the heavy $\mathrm{R}{\mathrm{Mn}}_{6}{\mathrm{Sn}}_{6}$.
