Large-scale supercomputer simulations predicted that the interlayer magnetic order in bilayer CrI3 can be switched between antiferromagnetic (AFM) and ferromagnetic (FM) by stacking reversal, corroborating existing experimental data. The microscopic origin of the magnetic order change were revealed through magnetic force theory calculations.
Significance and Impact
Stacking rotation and translation allow us to control and manipulate the interlayer magnetism of CrI3, as well as other 2D magnetic quantum materials.
