Gap generation in topological insulator surface states by nonferromagnetic magnets

Within a tight-binding approach, it is shown that, contrary to naive expectations, single-particle spectral gaps can be opened on the surface states of three-dimensional topological insulators by using commensurate out- and in-plane antiferromagnetic or ferrimagnetic insulating thin films.
