Eddy currents and current reversal in curved magnetic thin-film Josephson junctions
Einar Skoglund, Maxim A. Tjøtta, Sol H. Jacobsen
Real-space geometric curvature in magnetic thin films introduces a controllable mechanism for tailoring the pathways of superconducting steady-state Josephson currents via the prox…
Bending-strain effects in conventional superconductors and superconducting junctions
Kjell S. Heinrich, Henning G. Hugdal, Morten Amundsen +1
We consider the effect of bending-strain in thin films of clean, conventional superconductors (S), and the proximity-induced effect of this strain in SN bilayers with a normal meta…
Electrical control of superconducting spin valves using ferromagnetic helices
Tancredi Salamone, Henning G. Hugdal, Morten Amundsen +1
The geometrical properties of a helical ferromagnet are shown theoretically to control the critical temperature of a proximity-coupled superconductor. Using the Usadel equation for…
Non-constant geometric curvature for tailored spin-orbit coupling and chirality in superconductor-magnet heterostructures
Alv Johan Skarpeid, Henning G. Hugdal, Tancredi Salamone +2
We show that tailoring the geometric curvature profile of magnets can be used for bespoke design of an effective non-relativistic spin-orbit coupling, which may be used to control…
Interface probe for antiferromagnets using geometric curvature
Tancredi Salamone, Magnus Skjærpe, Henning G. Hugdal +2
We propose that geometric curvature and torsion may be used to probe the quality of an uncompensated antiferromagnetic interface, using the proximity effect. We study a helix of an…
High magnetic field superconductivity in a two-band superconductor
Tancredi Salamone, Henning G. Hugdal, Sol H. Jacobsen +1
When applying an external magnetic field to a superconductor, orbital and Pauli paramagnetic pairbreaking effects govern the limit of the upper critical magnetic field that can be…
Curvature control of the superconducting proximity effect in diffusive ferromagnetic nanowires
Tancredi Salamone, Henning G. Hugdal, Morten Amundsen +1
Coupling a conventional s-wave superconductor to a ferromagnet allows, via the proximity effect, to generate superconducting triplet correlations. This feature can be employed to a…
Curvature-induced long ranged supercurrents in diffusive SFS Josephson Junctions, with dynamic transition
Tancredi Salamone, Mathias B. M. Svendsen, Morten Amundsen +1
We report that spin supercurrents can be induced in diffusive SFS Josephson junctions without any magnetic misalignment or intrinsic spin orbit coupling. Instead, the pathway to sp…
Magnetic control of superconducting heterostructures using compensated antiferromagnets
Lina G. Johnsen, Sol H. Jacobsen, Jacob Linder
Due to the lack of a net magnetization both at the interface and in the bulk, antiferromagnets with compensated interfaces may appear incapable of influencing the phase transition…
Quantum kinetic equations and anomalous non-equilibrium Cooper pair spin accumulation in Rashba wires with Zeeman splitting
Sol H. Jacobsen, Jacob Linder
We derive the theoretical and numerical framework for investigating nonequilibrium properties of spin-orbit coupled wires with Zeeman splitting proximized by a superconductor in th…
Conservation of spin supercurrents in superconductors
Jabir Ali Ouassou, Sol H. Jacobsen, Jacob Linder
We demonstrate that spin supercurrents are conserved upon transmission through a conventional superconductor, even in the presence of spin-dependent scattering by impurities with m…
Critical Temperature and Tunneling Spectroscopy of Superconductor-Ferromagnet Hybrids with Intrinsic Rashba-Dresselhaus Spin-Orbit Coupling
Sol H. Jacobsen, Jabir Ali Ouassou, Jacob Linder
We investigate theoretically how the proximity effect in superconductor/ferromagnet hybrid structures with intrinsic spin-orbit coupling manifests in the density of states and crit…
Giant Triplet Proximity Effect in -biased Josephson Junctions with Spin-Orbit Coupling
Sol Jacobsen, Jacob Linder
In diffusive Josephson junctions the phase-difference between the superconductors strongly influences the spectroscopic features of the layer separating them. The observation o…
