Electronic properties of the Weyl semimetals Co${}_2$MnX (X=Si, Ge, Sn)

Abhishek Sharan, Felipe Crasto de Lima, Shoaib Khalid +2

Using first-principles electronic structure calculations, we show that ferromagnetic Heusler compounds Co${}_2$MnX (X= Si, Ge, Sn) present non-trivial topological characteristics and…
