Two dimensional magnetic materials, with tunable electronic properties could lead to new spintronic, magnetic and magneto-optic applications. Here, we explore intrinsic magnetic ordering in two dimensional monolayers of transition metal tri-halides (MX3, M = V, Cr, Mn, Fe and Ni, and X = F, Cl, Br and I), using density functional theory. We find that other than FeX3 family which has an anti-ferromagnetic ground state, rest of the trihalides are ferromagnetic. Amongst these the VX3 and NiX3 family are found to have the highest magnetic transition temperature, beyond the room temperature. In terms of electronic properties, the tri-halides of Mn and Ni are either half metals or Dirac half metals, while the tri-halides of V, Fe and Cr are insulators. Among all the trihalides studied in this paper, we find the existence of very clean spin polarized Dirac half metallic state in MnF3, MnCl3, MnBr3, NiF3 and NiCl3. These spin polarized Dirac half metals will be immensely useful for spin-current generation and other spintronic applications.
