However, when each ferromagnet layer is replaced by a single atomic layer of vdW magnetic insulators and electric transport through the bilayer is highly coherent, is the above picture still applicable? In a recent collaborative work [1], we argued that switching between layer-resolved collinear antiferromagnetic and ferromagnetic states in bilayer insulating CrI3 is achieved by tunneling-current-induced spin accumulation of opposite signs at metallic electrodes in contact with the respective CrI3 monolayers, which from a symmetry point of view is a general mechanism for switching between uniform and nonuniform magnetic states.
