Abstract

Kagome materials, with their corner-sharing triangular lattice, have attracted strong interest due to the interplay of correlations, magnetism, symmetry, and topology. Here, the authors engineer the magnetic landscape of ScMn${}_{6}$Sn${}_{6}$ via Ga doping to realize ScMn${}_{6}$(Sn${}_{0.78}$Ga${}_{0.22}$)${}_{6}$, which exhibits robust ferromagnetism below 375 K with an in-plane easy axis. High-resolution angle-resolved photoemission spectroscopy (ARPES) measurements reveal a Dirac cone near the Fermi energy, while theoretical calculations show that its gap can be tuned by the orientation of the magnetic moments. Additionally, a flat band spanning a large region of the Brillouin zone, originating from the Kagome lattice, is observed.
