**2. Recently developed 2D magnets**

In recent years, a great deal of new 2D magnets have been experimentally discovered and theoretically predicted. Here, we classified these emerging 2D intrinsic magnets into binary transition metal halogenides: CrX3 (X = Cl, Br, I) and ternary transition metal compounds, MPS3 (M = Fe, Ni, Mn), CrSBr and CrPS4. Their crystal structures, magnetic properties, and electronic band structures will be comprehensively described below.
