Evolution of the Chern Gap in Chern Magnet HoMn $_{6}$ Sn $_{6 - x}$ Ge $_{x}$

arXiv:2106.15494 · doi:10.3390/condmat7020040

Abstract

The Chern gap is a unique topological feature that can host non-abelian particles. The Kagome lattice forms a chern insulator with no gap. Upon the inclusion of magnetism the Kagome system hosts a Chern gap at the K points in the lattice. In this work, the effect of Ge doping on HoMn $_{6}$ Sn $_{6}$ is investigated. It is seen that with increased doping, a multi-stack Chern gap in formed in HoMn $_{6}$ Sn $_{6 - x}$ Ge $_{x}$ . In addition, the Chern gaps are much more pronounced and larger in energy in HoMn $_{6}$ Ge $_{6}$ then HoMn $_{6}$ Sn $_{6}$ .
