Probing Berry curvature in magnetic topological insulators through resonant infrared magnetic circular dichroism
Seul-Ki Bac, Florian le Mardelé, Jiashu Wang +16
Probing the quantum geometry and topology in condensed matter systems has relied heavily on static electronic transport experiments in magnetic fields. Yet, contact-free optical me…

Probing the magnetic band gap of the ferromagnetic topological insulator MnSbTe
Philipp Küppers, Jannik Zenner, Stefan Wimmer +4
Mn-rich MnSbTe is a ferromagnetic topological insulator with yet the highest Curie temperature T_C = 45-50 K. It exhibits a magnetic gap at the Dirac point of the topologic…
