Creating functional nanostructures for vortex manipulation in superconducting BiSrCaCuO thin films via focused He ion beam irradiation
Bernd Aichner, Christoph Schmid, Sandra Keppert +5
BiSrCaCuO (Bi-2212) is a highly anisotropic high-temperature superconductor exhibiting unique vortex dynamics due to its layered structure. Precise nanoscale pa…

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…
