Spin pumping from a ferromagnetic insulator into an altermagnet
Chi Sun, Jacob Linder
A class of antiferromagnets with spin-polarized electron bands, yet zero net magnetization, called altermagnets is attracting increasing attention due to their potential use in spi…
Barrier and finite size effects on the extension of topological surface-states into magnetic insulators
Eirik Holm Fyhn, Hendrik Bentmann, Jacob Linder
The interplay between magnetic and topological order can give rise to phenomena such as the quantum anomalous Hall effect. The extension of topological surface states into magnetic…
Converting a triplet Cooper pair supercurrent into a spin-signal
Sigrid Aunsmo, Jacob Linder
Superconductivity with spin-polarized Cooper pairs is known to emerge by combining conventional spinless superconductors with materials that have spin-dependent interactions, such…
RKKY interaction in triplet superconductors: Dzyaloshinskii-Moriya-type interaction mediated by spin-polarized Cooper pairs
Jabir Ali Ouassou, Takehito Yokoyama, Jacob Linder
The Ruderman--Kittel--Kasuya--Yosida (RKKY) interaction governs the coupling between localized spins and is strongly affected by the environment in which these spins reside. In sup…
Superconductor-altermagnet memory functionality without stray fields
Hans Gløckner Giil, Jacob Linder
A novel class of antiferromagnets, dubbed altermagnets, exhibit a non-relativistically spin-split band structure reminiscent of -wave superconductors, despite the absence of net…
On-off switch and sign change for non-local Josephson diode in spin-valve Andreev molecules
Erik Wegner Hodt, Jacob Linder
Andreev molecules consist of two coherently coupled Josephson junctions and permit non-local control over supercurrents. By making the barriers magnetic and thus creating a spin-va…
