Second, the influences of different stacking on the spin properties of SOD systems are discussed, from single-layer to bilayer and then to bulk with different phase combinations by taking advantage of the vdW nature, manifesting various spin phenomena such as the 120° in-plane antiferromagnetism, quantum spin liquid, and the Kondo effect. Then we give some examples of manipulation methods such as doping, strain, and electric field, which can induce the change of spin features.
