Nanoscale Spatial Tuning of Superconductivity in Cuprate Thin Films via Direct Laser Writing
Irene Biancardi, Valerio Levati, Jordi Alcalà +9
The paper shows that mask‑less direct laser writing can locally modify the oxygen content of YBCO thin‑film superconductors, creating sub‑micron grayscale patterns that tune the cr…
Extending Field Limits in Nanoscale Magnetic Imaging with Metamaterial-inspired Magnetic Flux Concentrators
A. Barrera, E. Fourneau, T. Pirottin +14
Many nanoscale magnetic imaging techniques are constrained by the maximum magnetic field that can be applied during measurements, due to geometrical limitations or interactions wit…
Probing Electromigration of Oxygen Vacancies in YBaCuO Devices by Multimodal X-ray Techniques
Caio C. Quaglio-Gomes, Stefan MarinkoviÄ, Elijah A. Abbey +5
Control of oxygen vacancies by electrical currents in complex oxides such as YBaCuO (YBCO) has attracted considerable interest due to the relative simplicity of it…
Effect of pulse duration on current-induced selective oxygen migration in high-Tc superconductors
Fridrich Egyenes, Daniel Stoffels, Stefan Marinkovic +6
High current densities can induce the directional diffusion of atoms in metallic films. In YBaCuO (YBCO), this electromigration process selectively acts on oxygen…
Magnetotransport signatures of spin-orbit coupling in high-temperature cuprate superconductors
Aleix Barrera, Huidong Li, Thomas Gunkel +4
Spin transport in superconductors offers a compelling platform to merge the dissipationless nature of superconductivity with the functional promise of spin-based electronics. A sig…
Misfit layer superconductors, tuneable bulk heterostructures with strong 2D effects
Tomas Samuely, Martin Gmitra, Tristan Cren +2
Atomically thin layered materials are systems with zero limit bulk-to-surface ratio. Their physical properties are determined by two-dimensionality and strongly affected by interfa…
