Electronic band structure changes across the antiferromagnetic phase transition of exfoliated MnPS probed by -ARPES
Jeff Strasdas, Benjamin Pestka, Milosz Rybak +17
Exfoliated magnetic 2D materials enable versatile tuning of magnetization, e.g., by gating or providing proximity-induced exchange interaction. However, their electronic band struc…
Mapping quantum Hall edge states in graphene by scanning tunneling microscopy
T. Johnsen, C. Schattauer, S. Samaddar +7
Quantum Hall edge states are the paradigmatic example of the bulk-boundary correspondence. They are prone to intricate reconstructions calling for their detailed investigation at h…
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…
Raman imaging of twist angle variations in twisted bilayer graphene at intermediate angles
A. Schäpers, J. Sonntag, L. Valerius +9
Van der Waals layered materials with well-defined twist angles between the crystal lattices of individual layers have attracted increasing attention due to the emergence of unexpec…
Evidence for local spots of viscous electron flow in graphene at moderate mobility
Sayanti Samaddar, Jeff Strasdas, Kevin Janßen +8
Dominating electron-electron scattering enables viscous electron flow exhibiting hydrodynamic current density patterns such as Poiseuille profiles or vortices. The viscous regime h…
Mn-rich MnSb2Te4: A topological insulator with magnetic gap closing at high Curie temperatures of 45-50 K
S. Wimmer, J. Sánchez-Barriga, P. Küppers +18
Ferromagnetic topological insulators exhibit the quantum anomalous Hall effect that might be used for high precision metrology and edge channel spintronics. In conjunction with sup…
