Quantum anomalous Hall edge channels survive up to the Curie temperature
Kajetan M. Fijalkowski, Nan Liu, Pankaj Mandal +4
Achieving metrological precision of quantum anomalous Hall resistance quantization at zero magnetic field so far remains limited to temperatures of the order of 20 mK, while the Cu…
Any Axion Insulator Must be a Bulk Three-Dimensional Topological Insulator
K. M. Fijalkowski, N. Liu, M. Hartl +11
In recent attempts to observe axion electrodynamics, much effort has focused on trilayer heterostructures of magnetic topological insulators, and in particular on the examination o…
Ubiquitous impact of localised impurity states on the exchange coupling mechanism in magnetic topological insulators
Thiago R. F. Peixoto, Hendrik Bentmann, Philipp Rüßmann +27
Since the discovery of the quantum anomalous Hall effect in the magnetically doped topological insulators (MTI) Cr:(Bi,Sb)Te and V:(Bi,Sb)Te, the search for the exc…
Coexistence of surface and bulk ferromagnetism mimics skyrmion Hall effect in a topological insulator
Kajetan M. Fijalkowski, Matthias Hartl, Martin Winnerlein +5
Here we report the investigation of the anomalous Hall effect in the magnetically doped topological insulator (V,Bi,Sb)2Te3. We find it contains two contributions of opposite sign.…
Breaking crystalline symmetry of epitaxial SnTe films by strain
Steffen Schreyeck, Karl Brunner, Laurens W. Molenkamp +7
SnTe belongs to the recently discovered class of topological crystalline insulators. Here we study the formation of line defects which break crystalline symmetry by strain in thin…
Scaling of the Quantum Anomalous Hall Effect as an Indicator of Axion Electrodynamics
S. Grauer, K. M. Fijalkowski, S. Schreyeck +5
We report on the scaling behavior of V-doped (Bi,Sb)Te samples in the quantum anomalous Hall regime for samples of various thickness. While previous quantum anomalous Hall…
