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.…
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…
Zero-field quantum anomalous Hall metrology as a step towards a universal quantum standard unit system
Martin Goetz, Kajetan M. Fijalkowski, Eckart Pesel +9
In the quantum anomalous Hall effect, the edge states of a ferromagnetically doped topological insulator exhibit quantized Hall resistance and dissipationless transport at zero mag…
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…
Impurity states in the magnetic topological insulator V:(Bi,Sb)Te
Thiago R. F. Peixoto, Hendrik Bentmann, Steffen Schreyeck +12
The ferromagnetic topological insulator V:(Bi,Sb)Te has been recently reported as a quantum anomalous Hall (QAH) system. Yet the microscopic origins of the QAH effect and t…
