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…
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…
YSGAG: The Ideal Substrate for YIG in Quantum Magnonics
Rostyslav O. Serha, Carsten Dubs, Christo Guguschev +8
Quantum magnonics leverages the quantum properties of magnons to advance nanoscale quantum information technologies. Ferrimagnetic yttrium iron garnet (YIG), known for exceptionall…
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…
Temporal Evolution of Defects and Related Electric Properties in He-Irradiated YBaCuO Thin Films
Sandra Keppert, Bernd Aichner, Philip Rohringer +8
Thin films of the superconductor YBaCuO (YBCO) were modified by low-energy light-ion irradiation employing collimated or focused He beams, and the long-term sta…
Vortex matching at 6 T in YBaCuO thin films by imprinting a 20 nm-periodic pinning array with a focused helium ion beam
Max Karrer, Bernd Aichner, Katja Wurster +9
Controlled engineering of vortex pinning sites in copper-oxide superconductors is a critical issue in manufacturing devices based on magnetic flux quanta. To address this, we emplo…
Phase purity and surface morphology of high-Jc superconducting Bi2Sr2Ca1Cu2O8+δ thin films
Sandra Keppert, Bernd Aichner, Rajdeep Adhikari +3
Bi2Sr2Ca1Cu2O8+d (Bi-2212) thin films with thicknesses less than 50 nm (<20 unit cells) are grown by pulsed laser deposition (PLD) onto (001) LaAlO3 (LAO) single crystal substrates…
Angle-dependent Magnetoresistance of an Ordered Bose Glass of Vortices in YBaCuO Thin Films with a Periodic Pinning~Lattice
Bernd Aichner, Lucas Backmeister, Max Karrer +5
The competition between intrinsic disorder in superconducting YBaCuO (YBCO) thin films and an ultradense triangular lattice of cylindrical pinning centers space…
Ordered Bose Glass of Vortices in Superconducting YBaCuO Thin Films with a Periodic Pin Lattice Created by Focused Helium Ion Irradiation
Lucas Backmeister, Bernd Aichner, Max Karrer +5
The defect-rich morphology of YBaCuO (YBCO) thin films leads to a glass-like arrangement of Abrikosov vortices which causes the resistance to disappear in vanis…
Vortex jets generated by edge defects in current-carrying superconductor thin strips
A. I. Bezuglyj, V. A. Shklovskij, B. Budinska +6
At sufficiently large transport currents , a defect at the edge of a superconducting strip acts as a gate for the vortices entering into it. These vortices form a je…
Rising speed limits for fluxons via edge quality improvement in wide MoSi thin films
