The magnetic field driven superconductor-metal transition in disordered hole-overdoped cuprates
Lina G. Johnsen
By solving the Bogoliubov-de Gennes equations for a -wave superconductor, we explore how the interplay between disorder and the orbital depairing of an external magnetic field i…
Spin injection and spin relaxation in odd-frequency superconductors
Lina G. Johnsen, Jacob Linder
The spin transport inside an odd-frequency spin-triplet superconductor differs from that of a conventional superconductor due to its distinct symmetry properties. We study spin tra…
Controllable enhancement of -wave superconductivity via magnetic coupling to a conventional superconductor
Linde A. B. Olde Olthof, Lina G. Johnsen, Jason W. A. Robinson +1
Unconventional superconductors are of high interest due to their rich physics, a topical example being topological edge-states associated with -wave superconductivity. A practic…
Magnon spin current induced by triplet Cooper pair supercurrents
Lina G. Johnsen, Haakon T. Simensen, Arne Brataas +1
At the interface between a ferromagnetic insulator and a superconductor there is a coupling between the spins of the two materials. We show that when a supercurrent carried by trip…
Superconductivity assisted change of the perpendicular magnetic anisotropy in V/MgO/Fe junctions
César González-Ruano, Diego Caso, Lina G. Johnsen +5
Controlling the perpendicular magnetic anisotropy (PMA) in thin films has received considerable attention in recent years due to its technological importance. PMA based devices usu…
Spin pumping between noncollinear ferromagnetic insulators through thin superconductors
Haakon T. Simensen, Lina G. Johnsen, Jacob Linder +1
Dynamical magnets can pump spin currents into superconductors. To understand such a phenomenon, we develop a method utilizing the generalized Usadel equation to describe time-depen…
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…
Superconductivity-induced change in magnetic anisotropy in epitaxial ferromagnet-superconductor hybrids with spin-orbit interaction
César González-Ruano, Lina G. Johnsen, Diego Caso +5
The interaction between superconductivity and ferromagnetism in thin film superconductor/ferromagnet heterostructures is usually reflected by a change in superconductivity of the S…
Controlling the Superconducting Transition by Rotation of an Inversion Symmetry-Breaking Axis
Lina G. Johnsen, Kristian Svalland, Jacob Linder
We consider a hybrid structure where a material with Rashba-like spin-orbit coupling is proximity coupled to a conventional superconductor. We find that the superconducting critica…
Magnetization reorientation due to the superconducting transition in heavy-metal heterostructures
Lina G. Johnsen, Niladri Banerjee, Jacob Linder
Recent theoretical and experimental work has demonstrated how the superconducting critical temperature () can be modified by rotating the magnetization of a single homogeneous…
