Abstract

The layered van der Waals antiferromagnet MnBi${}_{2}$Te${}_{4}$ has been predicted previously to realize the first intrinsic magnetic topological insulator. Here, the authors report spin- and angle-resolved photoemission experiments for the MnBi${}_{2}$Te${}_{4}$(0001) surface, revealing a surface ...
