Tailoring the properties of YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ 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 YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ (YBCO), this electromigration process selectively acts on oxygen a…

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 YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ Thin Films

Sandra Keppert, Bernd Aichner, Philip Rohringer +8

Thin films of the superconductor YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ (YBCO) were modified by low-energy light-ion irradiation employing collimated or focused He $^{+}$ beams, and the long-term sta…

Ordered Bose Glass of Vortices in Superconducting YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ 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 YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ (YBCO) thin films leads to a glass-like arrangement of Abrikosov vortices which causes the resistance to disappear in vanis…
