Sciences, Prague (host: Péter László és Bakonyi Imre)Electronic structure and 
transport in manganese tellurideTuesday, 24 January 2023, 10:00, KFKI Campus, 
Bldg. 1, 2nd floor, Conference RoomEffective models of semiconductor bands, 
describing their electronic structure, provide a shortcut to transport 
properties as compared to more general ab initio approach. Few of such models 
address magnetically ordered systems and of these, useful options to account 
for antiferromagnets (AFMs) are very limited. Manganese telluride is a 
well-established AFM semiconductor whose transport properties have been 
extensively studied [1] and an effective model of its valence band has been 
proposed [2]. In this talk, it will be shown how sensitive the electronic 
structure of MnTe is to its AFM magnetic order and the way to modelling the 
anisotropic magnetoresistance and anomalous Hall effect.[1] D. Kriegner, H.
