Electronic systems with flat bands are predicted to be a fertile ground for hosting emergent phenomena including unconventional magnetism and superconductivity1–15, but materials that manifest this feature are rare. Here, we use scanning tunnelling microscopy to elucidate the atomically resolved electronic states and their magnetic response in the kagome magnet Co3Sn2S2 (refs. 16–20). We observe a pronounced peak at the Fermi level, which we identify as arising from the kinetically frustrated… Expand

Tunable anomalous Hall conductivity through volume-wise magnetic competition in a topological kagome magnet
TLDR
The thermal and quantum tuning of Berry curvature induced AHC via external tuning of magnetic order is suggested and phase separation between ferro- and anti-ferromagnetic orders is found and that the volume-wise competition controls the anomalous Hall conductivity. Expand
Competing magnetic phases and fluctuation-driven scalar spin chirality in the kagome metal YMn6Sn6.
TLDR
This work identifies a number of nontrivial magnetic phases, explains their microscopic nature, and demonstrates that one of them hosts a large topological Hall effect (THE), and proposes a previously unidentified fluctuation-driven mechanism, which leads to the THE at elevated temperatures. Expand

Dirac cone, flat band and saddle point in kagome magnet YMn6Sn6
TLDR

Dirac fermions and flat bands in the ideal kagome metal FeSn
