Spatial resolution and point spread function of high-resolution scanning SQUID microscopy probes
Jan Ullmann, Katharina Kress, Timur Weber +5
Superconducting quantum interference devices (SQUIDs) show exceptional sensitivity to magnetic flux. In scanning SQUID microscopy (SSM), SQUID size and its distance to the sample a…
Tailoring the properties of YBaCuO thin films by 30 keV He irradiation: An enabling route to superconducting device nanopatterning
Bernd Aichner, Simon Koch, Philipp A. Korner +8
Focused helium ion beam (He-FIB) irradiation with 30 keV ions is a key tool for nanoscale patterning and defect engineering in high transition temperature (Tc) cuprate superconduct…
Structural Changes and Transport Properties of Locally Modified by a He Focused Ion Beam
Ross Carter, Robin Hutt, Paul Zimmermann +9
Irradiation of a material with ions can cause various defects that can lead to structural phase transitions and the modification of the material's properties. Here we study the irr…
Dually tunable YBCO coplanar waveguide resonators based on helium-ion-generated Josephson inductances
Kenny Fohmann, Timo J. Glebe-Märklin, Benedikt Wilde +5
Superconducting microwave circuits with and without Josephson inductances are the Swiss Army knife for many experiments and technologies from quantum information science to astroph…
Electric-Field Control of Quantum Tunneling Regimes in Focused He-Ion-Beam-Irradiated Oxide Interfaces
Yu Chen, Maria D'Antuono, Robin Hutt +6
Helium focused ion beam irradiation enables the fabrication of tunnel field-effect transistors based on two-dimensional electron systems (2DESs) at an oxide interface.High resoluti…
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…
