By combining symmetry analysis and direct density functional calculations including the spin-orbit coupling, we demonstrate that anomalous Hall effect can be observed in not only germanides with general formula RMn 2 Ge 2, where R is a rare-earth ion or Y. Our calculations predict a large anomalous Hall conductivity in LaMn 2 Si 2, with a non-zero ₗₘ^{{AH}} component of −360 S/cm, accompanied by a pronounced magneto-optical response. Remarkably, electron doping of LaMn 2 Si 2 is expected to substantially enhance the Hall conductivity, with values reaching up to −650 S/cm. These results suggest that silicides with general formula RM 2 Si 2 can be an interesting platform for studying anomalous Hall effect.
