Intrinsic magnetic topological insulators in van der Waals layered MnBi 2 Te 4 -family materials

, including an antiferromagnetic topological insulator with the long-sought topological axion states on the surface, a type II magnetic Weyl semimetal with one pair of Weyl points, as well as a collection of intrinsic axion insulators and QAH insulators in even- and odd-layer films, respectively.
