Microscopic origins and stability of the ferromagnetism in Co${}_3$Sn${}_2$S${}_2$

I. V. Solovyev, S. A. Nikolaev, A. V. Ushakov +3

Based on the density functional theory, we examine the origin of ferromagnetism in the Weyl semimetal Co${}_3$Sn${}_2$S${}_2$ using different types of response theories. We argue that th…
