Magnetic topological insulators – towards higher transition temperature

Ferromagnetic order in topological insulators is essential to observe quantum anomalous Hall effect and several unique effects. We will show recent progress towards higher transition temperature in MnSb₂Te₄ thin films. This material has a transition temperature of about 50 K in contrary to the previously observed transition temperature of 10 K in Bi₂MnTe₄.
