Synthetic Altermagnets
Ali Asgharpour, Bert Koopmans, Rembert A. Duine
Altermagnets, a distinct class of antiferromagnets with electronic structures resembling those of d-wave superconductors, exhibit intriguing properties that have gained significant…
Coherent control of terahertz-scale spin resonances using optical spin-orbit torques
Julian Hintermayr, Paul M. P. van Kuppevelt, Bert Koopmans
Using optically generated spin-orbit torques induced by the heavy metal Pt we demonstrate coherent control of GHz ferromagnetic resonances in Pt/Co/Pt multilayers as well as sub-TH…
Explaining all-optical switching in ferrimagnets with heavy rare-earth elements by varying the spin-flip scattering probability of Gd in CoGd alloys and Co/Gd bilayers
Julian Hintermayr, Bert Koopmans
Using the microscopic three temperature model, we simulate single-pulse all-optical switching (AOS) in alloys and bilayers consisting of Co and Gd. In particular, we investigate it…
Spin-polarized hot electron transport versus spin pumping mediated by local heating
Maarten Beens, Koen de Mare, Rembert Duine +1
A `toy model' - aimed at capturing the essential physics - is presented that jointly describes spin-polarized hot electron transport and spin pumping driven by local heating. These…
Comparing all-optical switching in synthetic-ferrimagnetic multilayers and alloys
Maarten Beens, Mark L. M. Lalieu, Axel J. M. Deenen +2
We present an experimental and theoretical investigation of all-optical switching by single femtosecond laser pulses. Our experimental results demonstrate that, unlike rare earth-t…
