Ordered Bose Glass of Vortices in Superconducting YBa${}_2$Cu${}_3$O${}_{7-\delta }$ 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${}_{7-\delta }$ (YBCO) thin films leads to a glass-like arrangement of Abrikosov vortices which causes the resistance to disappear in vanis…
