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…

Vortex matching at 6 T in YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ 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…
