Visualizing the breakdown of the quantum anomalous Hall effect
George M. Ferguson, Run Xiao, Anthony R. Richardella +3
The creation of topologically non-trivial matter across electronic, mechanical, cold-atom, and photonic platforms is advancing rapidly, yet understanding the breakdown of topologic…
Imaging signatures of edge currents in a magnetic topological insulator
G. M. Ferguson, Run Xiao, Anthony R. Richardella +3
Magnetic topological insulators (MTIs) host topologically protected edge states, but the role that these edge states play in electronic transport remains unclear. Using scanning su…
Direct visualization of electronic transport in a quantum anomalous Hall insulator
G. M. Ferguson, Run Xiao, Anthony R. Richardella +3
A quantum anomalous Hall (QAH) insulator is characterized by quantized Hall and vanishing longitudinal resistances at zero magnetic field that are protected against local perturbat…
Scanning SQUID microscopy in a cryogen-free dilution refrigerator
D. Low, G. M. Ferguson, Alexander Jarjour +4
We report a scanning superconducting quantum interference device (SQUID) microscope in a cryogen-free dilution refrigerator with a base temperature at the sample stage of at least…
