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 $30 keV$ focused He ion beam (He-FIB) with a wide range of irradiation doses $D = 100$ to $1000 ions/nm$ we fabricated Josephson and resistive barriers wi…

On the coupling of magnetic moments to superconducting quantum interference devices

J. Linek, M. Wyszynski, B. MÃ¼ller +4

We investigate the coupling factor $I ¨ _{I^} ¼$ that quantifies the magnetic flux $I^¦$ per magnetic moment $I^¼$ of a point-like magnetic dipole that couples to a superconducting quantum…

NanoSQUIDs from YBa $_{2}$ Cu $_{3}$ O $_{7}$ /SrTiO $_{3}$ superlattices with bicrystal grain boundary Josephson junctions

J. Lin, J. Linek, R. Kleiner +1

We report on the fabrication and characterization of nanopatterned dc SQUIDs with grain boundary Josephson junctions based on heteroepitaxially grown YBa $_{2}$ Cu $_{3}$ O $_{7}$ (YBCO)/ SiT…
