Electrical manipulation of oxygen stoichiometry in multiterminal YBaCuO junctions
Daniel Stoffels, Caio C. Quaglio-Gomes, Nicolas Lejeune +7
Local manipulation of oxygen stoichiometry offers a route to control the electronic properties of complex oxides, yet the selective modification of individual current-carrying bran…
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 Marinković, 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 its…
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 a…
Nanoscale Spatial Tuning of Superconductivity in Cuprate Thin Films via Direct Laser Writing
Irene Biancardi, Valerio Levati, Jordi Alcalà +9
Cuprate high-temperature superconductors, such as Yttrium Barium Copper Oxide (YBCO), are extremely promising for emerging technologies such as low-power computing, data storage, q…
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…
