Query: Electronic and magnetic properties of single-layer MPX$_3$ metal
  phosphorous trichalcogenides   We systematically investigate the electronic structure and magnetic
properties of two dimensional (2D) MPX$_3$ (M= V, Cr, Mn, Fe, Co, Ni, Cu, Zn,
and X = S, Se, Te) transition metal chacogenophosphates to examine their
potential role as single-layer van der Waals materials that exhibit magnetic
order. Our {\em ab initio} calculations predict that most of these single-layer
materials are antiferromagnetic semiconductors. The band gaps of the
antiferromagnetic states decrease as the atomic number of the chalcogen atom
increases (from S to Se, Te), leading in some cases to half-metallic
ferromagnetic states or to non-magnetic metallic states. We find that the phase
transition from antiferromagnetic semiconductor to ferromagnetic half-metal can
be controlled by gating or by strain engineering. The sensitive interdependence
we find between magnetic, structural, and electronic properties establishes the
potential of this 2D materials class for applications in spintronics.
