Abstract: In a kagome lattice, the time reversal symmetry can be broken by a staggered magnetic flux emerging from ferromagnetic ordering and intrinsic spin-orbit coupling, leading to several well-separated nontrivial Chern bands and intrinsic quantum anomalous Hall effect. Based on this idea and ab initio calculations, we propose the realization of the intrinsic quantum anomalous Hall effect in the single layer Cs 2 Mn 3 F 12 kagome lattice and on the (001) surface of a Cs 2 LiMn 3 F 12 single crystal by modifying the carrier coverage on it, where the band gap is around 20 meV.
