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…
Mechanisms of skyrmion collapse revealed by sub-nm maps of the transition rate
Florian Muckel, Stephan von Malottki, Christian Holl +5
Magnetic skyrmions are key candidates for novel memory, logic, and neuromorphic computing. An essential property is their topological protection caused by the whirling spin texture…
Strong and Weak Three-Dimensional Topological Insulators Probed by Surface Science Methods
Markus Morgenstern, Christian Pauly, Jens Kellner +12
We review the contributions of surface science methods to discover and improve 3D topological insulator materials, while illustrating with examples from our own work. In particular…
Probing the Pinning Strength of Magnetic Vortex Cores with sub-nm Resolution
Christian Holl, Marvin Knol, Marco Pratzer +4
Topological magnetic textures such as vortex cores or skyrmions are key candidates for non-volatile information processing. This exploits the texture movement by current pulses tha…
Exfoliated hexagonal BN as gate dielectric for InSb nanowire quantum dots with improved gate hysteresis and charge noise
Felix Jekat, Benjamin Pestka, Diana Car +8
We characterize InSb quantum dots induced by bottom finger gates within a nanowire that is grown via the vapor-liquid-solid process. The gates are separated from the nanowire by an…
