Angle-dependent Magnetoresistance of an Ordered Bose Glass of Vortices in YBa2Cu3O7-δ Thin Films with a Periodic Pinning Lattice
Autor: Bernd Aichner, Lucas Backmeister, Max Karrer, Katja Wurster, Reinhold Kleiner, Edward Goldobin, Dieter Koelle, Wolfgang Lang
Publikováno v: Condensed Matter, Vol 8, Iss 2, p 32 (2023)
The competition between intrinsic disorder in superconducting YBa2Cu3O7−δ (YBCO) thin films and an ultradense triangular lattice of cylindrical pinning centers spaced at 30 nm intervals results in an ordered Bose glass phase of vortices. The sampl

Ordered Bose Glass of Vortices in Superconducting YBa2Cu3O7−δ Thin Films with a Periodic Pin Lattice Created by Focused Helium Ion Irradiation

The defect-rich morphology of YBa2Cu3O7−δ (YBCO) thin films leads to a glass-like arrangement of Abrikosov vortices which causes the resistance to disappear in vanishing current densities. This vortex glass consists of entangled vortex lines and i

Publikováno v: Physical Review Applied. 11
To fabricate high-${T}_{c}$ Josephson junctions, YBa${}_{2}$Cu${}_{3}$O${}_{7}$ (YBCO) bicrystal grain-boundary junction technology is used most frequently, as it is simple and yields junctions of reasonable quality. This technique only allows placem

Publikováno v: Physical Review B. 98
We study $\mathrm{Nb}\ensuremath{-}{\mathrm{AlO}}_{x}$-Nb Josephson junctions (JJs) with a phase-discontinuity $\ensuremath{\kappa}$ created by a pair of current injectors attached to one of the Nb electrodes. For $\ensuremath{\kappa}\ensuremath{\app

TunableφJosephson junction ratchet

Publikováno v: Physical Review E. 94
We demonstrate experimentally the operation of a deterministic Josephson ratchet with tunable asymmetry. The ratchet is based on a φ Josephson junction with a ferromagnetic barrier operating in the underdamped regime. The system is probed also under

Model $I$--$V$ curves and figures of merit of underdamped deterministic Josephson ratchets
Autor: Edward Goldobin, Reinhold Kleiner, R. Menditto, Dieter Koelle
We propose simple models for the current-voltage characteristics of typical Josephson ratchets. We consider the case of a ratchet working against a constant applied counter force and derive analytical expressions for the key characteristics of such a
