Abstract: Septuple layers of MnBi2Te4 type are important building blocks of magnetic topological insulators and semimetals but also examples of two-dimensional magnetic materials with critical temperatures up to a few tens of Kelvin. Using density functional theory (DFT) we study the exchange interactions in MnBi2Te4, MnBi2Se4, and MnSb2Te4 films to highlight the importance of higher-order terms and the contributions of relativistic anisotropic interactions. We also discuss the possibility to induce Dzyaloshinskii-Moriya interaction by gating with an external electric field.
