Intrinsic ferromagnetism and restrictive thermodynamic stability in MA${}_2$N${}_4$ and Janus VSiGeN${}_4$ monolayers

Dibyendu Dey, Avijeet Ray, Liping Yu

The seminal experimental discovery of the remarkably stable MoSi${}_2$N${}_4$ monolayer has led to a handful of predicted magnetic two-dimensional (2D) materials in the MA${}_2$Z${}_4$ fam…
