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…
YBaCuO nano-constriction Josephson junctions and SQUIDs fabricated by focused helium-ion-beam irradiation
Christoph Schmid, Christopher Buckreus, David Haas +9
By focused He ion beam irradiation, epitaxially grown YBaCuO (YBCO) thin films can be driven from the superconducting to the insulating state with in…
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…
Why shot noise does not generally detect pairing in mesoscopic superconducting tunnel junctions
Jiasen Niu, Koen M. Bastiaans, Jianfeng Ge +10
The shot noise in tunneling experiments reflects the Poissonian nature of the tunneling process. The shot noise power is proportional to both the magnitude of the current and the e…
Temporal evolution of electric transport properties of YBCO Josephson junctions produced by focused Helium ion beam irradiation
M. Karrer, K. Wurster, J. Linek +4
Using a focused He ion beam (He-FIB) with a wide range of irradiation doses to we fabricated Josephson and resistive barriers wi…
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…
Angular magnetic-field dependence of vortex matching in pinning lattices fabricated by focused or masked helium ion beam irradiation of superconducting YBaCuO thin films
Bernd Aichner, Kristijan L. Mletschnig, Benedikt Müller +6
The angular dependence of magnetic-field commensurability effects in thin films of the cuprate high-critical-temperature superconductor YBaCuO (YBCO) with an ar…
Ultradense Tailored Vortex Pinning Arrays in Superconducting YBaCuO Thin Films Created by Focused He Ion Beam Irradiation for Fluxonics Applications
Bernd Aichner, Benedikt Müller, Max Karrer +9
Magnetic fields penetrate a type-II superconductor as magnetic flux quanta, called vortices. In a clean superconductor they arrange in a hexagonal lattice, while by adding periodic…
Josephson junctions and SQUIDs created by focused helium ion beam irradiation of YBaCuO
B. Müller, M. Karrer, F. Limberger +6
By scanning with a focused He ion beam (He-FIB) across YBaCuO (YBCO) thin film microbridges, we create Josephson barriers with critical current dens…
