Description

Chromium halides such as CrI3 have attracted interest recently. They possess the remarkable property of sustaining long-range magnetic order down to the thickness of only a few layers [1, 2]. However, CrI3 lacks Dzyaloshinskyii– Moriya interaction (DMI) due to inversion center present between the adjacently bonded Chromium atoms.

The inversion center can be removed through the fabrication of Janus Monolayers by adding another trihalide along with Iodine to synthesize the material, that is to grow Janus monolayers Cr(I, X)₃ where X is another halide such as Cl or Br [3].

Previous work has predicted non-trivial spin textures such as out-of-plane Néel-type cycloid with metastable Domain-Wall Skyrmions (DWS) in Cr(I,Br)₃ or stabilization of bimerons in Cr(I,Cl)₃ monolayers [3].

However, magnetic properties of these Janus bilayers have yet to be explored.
