Tunable Phonon-Driven Magnon Spin Currents in Altermagnets
Sofie Helene Ursin, Mathias Kläui, Kjetil M. D. Hals
Altermagnets have recently attracted considerable interest due to their unique symmetry-governed spintronic properties. Here, we investigate phonon-induced magnon spin currents in…
Strain-induced manipulation of non-collinear antiferromagnets
Mithuss Tharmalingam, Feodor Svetlanov Konomaev, Kjetil M. D. Hals
In recent years, there has been growing interest in harnessing non-collinear antiferromagnets (NCAFMs) for applications in antiferromagnetic spintronics. A key requirement for thei…
Amplifying the antiferromagnetic spin Seebeck effect through topological magnons
Feodor Svetlanov Konomaev, Kjetil M. D. Hals
Topological magnons emerge as topologically protected spin wave states at the edges of magnets. Here, we theoretically explore how these surface states can be harnessed to amplify…
Voltage-Controlled High-Bandwidth Terahertz Oscillators Based On Antiferromagnets
Mike A. Lund, Davi R. Rodrigues, Karin Everschor-Sitte +1
Producing compact voltage-controlled frequency generators and sensors operating in the terahertz (THz) regime represents a major technological challenge. Here, we show that noncoll…
Spin pumping in noncollinear antiferromagnets
Mike A. Lund, Akshaykumar Salimath, Kjetil M. D. Hals
The ac spin pumping of noncollinear antiferromagnets is theoretically investigated. Starting from an effective action description of the spin system, we derive the Onsager coeffici…
Spin-wave driven bidirectional domain wall motion in kagome antiferromagnets
Davi R. Rodrigues, Akshaykumar Salimath, Karin Everschor-Sitte +1
We predict a mechanism to controllably manipulate domain walls in kagome antiferromagnets via a single linearly polarized spin-wave source. We show by means of atomistic spin dynam…
