Electric and spin current vortices in altermagnets
Arsen Herasymchuk, Karl Bergson Hallberg, Erik Wegner Hodt +3
Altermagnets constitute a class of collinear magnets with momentum-dependent spin splitting and vanishing net magnetization. Direct observation of the characteristic altermagnetic…
Phonon-enhanced optical spin-conductivity and spin-splitter effect in altermagnets
Erik Wegner Hodt, Alireza Qaiumzadeh, Jacob Linder
Collinear antiferromagnets with nonrelativistic spin-split bands and no net magnetization, called altermagnets, show interesting transport properties due to their unique band struc…
Orbital splitter effect and spatial resolution of current-induced orbital accumulation
Niels Henrik Aase, Erik Wegner Hodt, Karl Bergson Hallberg +2
The emergence of an orbital angular momentum (OAM) response to a charge current holds promise for technological applications, allowing electrical control of magnetization dynamics.…
Visualization of spin-splitter effect in altermagnets via non-equilibrium Green functions on a lattice
Karl Bergson Hallberg, Erik Wegner Hodt, Jacob Linder
When a charge current is injected into an altermagnet along a suitable crystallographic direction, a transverse spin current can be generated. This so-called spin-splitter effect d…
The fate of -wave spin polarization in helimagnets with Rashba spin-orbit coupling
Erik Wegner Hodt, Hendrik Bentmann, Jacob Linder
It has recently been realized that magnetic systems with coplanar magnetic order that are invariant under the combined operation of time-reversal and translation with half a unit c…
