Cavity-mediated impact of superconductors on ferromagnetic insulators
Janssønn, Andreas T. G. (Doctoral theses at NTNU;2022:254, Doctoral thesis, 2022)This dissertation is a presentation of the research conducted during three years at the QuSpin Center for Quantum Spintronics, on the cavity-mediation of interactions between ferromagnetic insulators (FI) and superconductors ... -
Controlling superconducting spin flow with spin-flip immunity using a single homogeneous ferromagnet
Jacobsen, Sol; Kulagina, Iryna; Linder, Jacob (Journal article; Peer reviewed, 2016)Spin transport via electrons is typically plagued by Joule heating and short decay lengths due to spin-flip scattering. It is known that dissipationless spin currents can arise when using conventional superconducting ... -
Critical temperature and tunneling spectroscopy of superconductor-ferromagnet hybrids with intrinsic Rashba-Dresselhaus spin-orbit coupling
Jacobsen, Sol; Ouassou, Jabir Ali; Linder, Jacob (Journal article, 2015)We investigate theoretically how the proximity effect in superconductor/ferromagnet hybrid structures with intrinsic spin-orbit coupling manifests in two measurable quantities, namely the density of states and critical ... -
Curvature in Superconductor-Ferromagnet structures
Svendsen, Mathias Bo Mjøen (Master thesis, 2021)Innføring av superledende spinntroniske enheter er sett på som en mulig løsning til det enorme energitapet på grunn av Joulsk varme i dagens datamaskiner. Superledende spinntroniske enheter er både energi- og plass-effektive, ... -
Curvature-induced long-range supercurrents in diffusive superconductor-ferromagnet-superconductor Josephson junctions with a dynamic 0−π transition
Salamone, Tancredi; Svendsen, Mathias Bo Mjøen; Amundsen, Morten; Jacobsen, Sol (Peer reviewed; Journal article, 2021)We report that spin supercurrents can be induced in diffusive superconductor-ferromagnet-superconductor Josephson junctions without any magnetic misalignment or intrinsic spin-orbit coupling. Instead, the pathway to ... -
Diffusive Curved Superconductor-Ferromagnet Proximity Systems in and out of Equilibrium
Skarpeid, Alv Johan (Master thesis, 2022)I strukturer med superledere og ferromagneter kan superledende korrelasjoner lekke et lite stykke inn i ferromagneten; dette er den superledende proksimitetseffekten. Hybridsystemer hvor denne effekten er signifikant kan ... -
Giant triplet proximity effect in π-biased Josephson junctions with spin-orbit coupling
Jacobsen, Sol; Linder, Jacob (Journal article, 2015)In diffusive Josephson junctions the phase difference φ between the superconductors strongly influences the spectroscopic features of the layer separating them. The observation of a uniform minigap and its phase modulation ... -
Quasiclassical theory for the superconducting proximity effect in Dirac materials
Hugdal, Henning Goa; Linder, Jacob; Jacobsen, Sol (Journal article, 2017)We derive the quasiclassical non-equilibrium Eilenberger and Usadel equations to first order in quantities small compared to the Fermi energy, valid for Dirac edge and surface electrons with spin-momentum locking p· σ¯, ...
