Fig. 1: Structural and magnetic properties of Janus NiXY monolayers (X, Y=Cl, Br, I).
From: Dzyaloshinskii–Moriya interaction manipulation in multiferroic Janus monolayers
a Top and side view of the Janus NiXY monolayers. Gray, purple, and orange balls denote Ni, X, and Y atoms, respectively. b The schematic of magnetic interactions in monolayer NiXY. Dashed purple lines denote the chemical bonds between Ni and ligands. Orange arrows denote the directions of the horizontal component of DMI between each nearest Ni-Ni pair, with the vertical components of DMI symbolled beside each arrow. Light purple lines indicate the mirrors.
