Abstract

Kagome Chern Magnets are lattices which host a Chern state when they are non-magnetic and a Chern Gap when they become magnetic. These Chern gaps can host fractional Chern Fermions. There has been extensive research in the RMn $_{6}$ Sn $_{6}$ system which hosts a small Chern gap with many trivial bands surrounding them. RMn $_{6}$ Ge $_{6}$ is studied theoretically in order to find a more insulating Kagome magnetic with fewer bands near the Chern gap.
