Magneto-optical Response of 5-SL MnBi${}_2$Te${}_4$ in Spin-Flip States

Shahid Sattar, Roman Stepanov, A. H. MacDonald +1

Magneto-optical effects like Kerr and Faraday rotations provide a direct probe of topological order in thin films of the magnetic topological insulator MnBi${}_2$Te${}_4$ (MBT). Motiva…
