Transport properties of semiconductors depend on several factors, arguably the most prominent one being the Fermi level. In magnetically ordered materials, direction of magnetic moments is another such factor. Hexagonal (NiAs-type) MnTe is a semiconductor with moderate band gap, room temperature resistivity of about few Ohm.cm and the Neel temperature slightly above room temperature. I will talk both about experimental and theoretical progress on this material and highlight two transport phenomena: the anisotropic magnetoresistance (AMR) and the anomalous Hall effect (AHE). In collinear antiferromagnets, the latter is specific to a class of systems called 'altermagnets' and since this concept is non-relativistic while the AHE relies on the spin-orbit interaction (in collinear systems), detailed understanding of the electronic structure at the scale comparable to realistic Fermi energy is necessary. Direction of magnetic moments has a minor effect here but still controls not only the AMR but, via wave-function properties (such as the Berry curvature) also the odd part of Rxy while the magnetic moments remain in the xy-plane.
