Quasiclassical theory for antiferromagnetic metals

EH Fyhn, A Brataas, A Qaiumzadeh, J Linder - Physical Review B, 2023 - APS
Unlike ferromagnetism, antiferromagnetism cannot readily be included in the quasiclassical
Keldysh theory because of the rapid spatial variation in the directions of of the magnetic …

Design of supercurrent diode by vortex phase texture

Y Fukaya, MT Mercaldo, D Margineda, A Crippa… - arXiv preprint arXiv …, 2024 - arxiv.org
We investigate supercurrent nonreciprocal effects in a superconducting weak-link hosting
distinct types of vortices. We demonstrate how the winding number of the vortex, its spatial …

Superconducting vortices in half-metals

EH Fyhn, J Linder - Physical Review B, 2019 - APS
When the impurity mean free path is short, only spin-polarized Cooper pairs which are
nonlocally and antisymmetrically correlated in time may exist in a half-metallic ferromagnet …

Vortex spin valve on a topological insulator

M Amundsen, HG Hugdal, A Sudbø, J Linder - Physical Review B, 2018 - APS
Spin-valve structures are usually associated with the ability to modify the resistance of
electrical currents. We here demonstrate a profoundly different effect of a spin-valve. In …

Paramagnetic Meissner Effect and Non-Equilibrium Vortices in Superconductor/Normal-Metal Structures

H Falch - 2023 - ntnuopen.ntnu.no
Proksimitetseffekten mellom en superleder og et normalt metall fører til at noe av
superledningen lekker inn i normalmetallet. Dette betyr at superledende virvler kan oppstå i …

Electronic structure of a mesoscopic superconducting disk: Quasiparticle tunneling between the giant vortex core and the disk edge

AV Samokhvalov, IA Shereshevskii, NK Vdovicheva… - Physical Review B, 2019 - APS
The electronic structure of the giant vortex states in a mesoscopic superconducting disk is
studied in a dirty limit using the Usadel approach. The local density of states profiles are …
