III. Doping-induced interlayer magnetic phase transition

Free carriers may induce the magnetic transition between interlayer FM and AFM orders.

The left panel is an example of bilayer CrCl3 under electron and hole dopings. Both high-temperature (HT) and low-temperature (LT) interlayer stackings are considered.

IV. Potential Charger-transfer-induced magnetoelectric coupling

Given the band alignment and vdW magnets, which are sensitive to doped free carriers, the following heterostructures may exhibit intrinsic charge transfer, leading to field-controllable doping and magnetoelectric coupling:

CrCl3/SrTiO3,

CrCl3/PbTe

CrCl3/PbSe,

CrI3/SrTiO3,

CrI3/PbTe,

CrI3/PbSe,

NiI2/SrTiO3,

NiI2/PbSe,

NiI2/PbTe,

NiI2/SnSe.
