Two-orbital effective model for magnetic Weyl semimetal in Kagome-lattice shandite

Akihiro Ozawa, Kentaro Nomura

We construct a two-orbital effective model for a ferromagnetic Kagome-lattice shandite, ${\mathrm{Co}}_3{\mathrm{Sn}}_2{\mathrm{S}}_2$, a candidate material of magnetic Weyl semimetals, by considering o…
