Anomalous Hall effect in distorted kagome magnets (Nd, Sm)Mn6Sn6
Abstract
We report magnetic and electrical properties for single crystals of NdMn6Sn6 and SmMn6Sn6. They crystallize into a structure which has distorted, Mn-based kagome lattices, compared to the pristine kagome lattices in heavy-rare-earth-bearing RMn6Sn6 compounds. They are hightemperature 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 RMn6Sn6.
