Prediction and observation of the first antiferromagnetic topological insulator

Mikhail M. Otrokov, Ilya I. Klimovskikh, Hendrik Bentmann +41

Magnetic topological insulators (MTIs) are narrow gap semiconductor materials that combine non-trivial band topology and magnetic order. Unlike their nonmagnetic counterparts, MTIs…
