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.
