The electronic flat band in kagome lattices offers a promising platform for exploring electron-correlated and topological phenomena, yet its potential for device functionality remains underexplored. Here, the authors investigate Co₃Mo films, revealing enhanced perpendicular magnetic anisotropy, large coercive field, and anomalous Hall effect mediated by kagome lattice flat bands close to the Fermi level, positioning Co₃Mo as a candidate for topological magnetic devices.
