Molecular Beam Epitaxy of a Half-Heusler Topological Superconductor Candidate YPtBi
Jiwoong Kim, Kajetan M. Fijalkowski, Johannes Kleinlein +6
The search for topological superconductivity has motivated investigations into materials that combine topological and superconducting properties. The half-Heusler compound YPtBi ap…
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…
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.…
Non-Majorana Origin of the Half-Quantized Conductance Plateau in Quantum Anomalous Hall Insulator and Superconductor Hybrid Structures
Morteza Kayyalha, Di Xiao, Ruoxi Zhang +14
A quantum anomalous Hall (QAH) insulator coupled to an s-wave superconductor is predicted to harbor a topological superconducting phase, the elementary excitations of which (i.e. M…
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…
