Surface states and Rashba-type spin polarization in antiferromagnetic MnBi${}_2$Te${}_4$

Abstract

The layered van der Waals antiferromagnet MnBi${}_2$Te${}_4$ has been predicted to combine the band ordering of archetypical topological insulators such as Bi${}_2$Te${}_3$ with the magnetism of Mn, making this material a viable candidate for the realization of various magnetic topological states. We have systematically investigated the surface electronic structure of MnBi${}_2$Te${}_4$(0001) single crystals by use of spin- and angle-resolved photoelectron spectroscopy experiments. In line with theoretical predictions, the results reveal a surface state in the bulk band gap and they provide evidence for the influence of exchange interaction and spin-orbit coupling on the surface electronic structure.
