Imaging short- and long-range magnetic order in a quantum anomalous Hall insulator
Andriani Vervelaki, Boris Gross, Daniel Jetter +11
The quantum anomalous Hall effect has been observed in several magnetically doped topological insulators, where its robustness and macroscopic magnetization properties have been ta…
Characteristic lengthscales of the electrically-induced insulator-to-metal transition
Theodor Luibrand, Adrien Bercher, Rodolfo Rocco +16
Some correlated materials display an insulator-to-metal transition as the temperature is increased. In most cases this transition can also be induced electrically, resulting in vol…
Optical imaging of strain-mediated phase coexistence during electrothermal switching in a Mott insulator
Matthias Lange, Stefan Guénon, Yoav Kalcheim +6
Resistive-switching -- the current-/voltage-induced electrical resistance change -- is at the core of memristive devices, which play an essential role in the emerging field of neur…
Impedance spectroscopy of ferroelectrics: The domain wall pinning element
M. Becker, C. J. Burkhardt, R. Kleiner +1
We introduce an equivalent-circuit element based on the theory of interface pinning in random systems, to analyze the contribution of domain wall motion below the coercive field to…
Characterizing dielectric properties of ultra-thin films using superconducting coplanar microwave resonators
Nikolaj G. Ebensperger, Benedikt Ferdinand, Dieter Koelle +3
We present an experimental approach for cryogenic dielectric measurements on ultra-thin insulating films. Based on a coplanar microwave waveguide design we implement superconductin…
Electrical-transport characteristics of as-grown and oxygen-reduced LaCeMnO films: calculation of hopping energies, Mn valences, and carrier localization lengths
Andreas Thiessen, Elke Beyreuther, Robert Werner +3
Presently, cerium-doped LaMnO is vividly discussed as an electron-doped counterpart prototype to the well-established hole-doped mixed-valence manganites. Here, LaCe$_{…
