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…
Enhancing All-Optical Switching of Magnetization by He Ion Irradiation
Pingzhi Li, Johannes W. van der Jagt, Maarten Beens +8
All-optical switching (AOS) of magnetization by a single femtosecond laser pulse in Co/Gd based synthetic ferrimagnets is the fastest magnetization switching process. On the other…
Probing Laser-Induced Spin-Current Generation in Synthetic Ferrimagnets Using Spin Waves
Tom Lichtenberg, Youri L. W. van Hees, Maarten Beens +4
Several rare-earth transition-metal ferrimagnetic systems exhibit all-optical magnetization switching upon excitation with a femtosecond laser pulse. Although this phenomenon is ve…
Laser induced ultrafast Gd 4f spin dynamics in Co100-xGdx alloys by means of time-resolved XMCD
T. Ferté, M. Beens, G. Malinowski +8
We have studied the laser induced ultrafast quenching of Gd 4f magnetic order in ferrimagnetic Co100-xGdx alloys to highlight the role of the inter-atomic exchange coupling. We hav…
Modeling ultrafast demagnetization and spin transport: the interplay of spin-polarized electrons and thermal magnons
Maarten Beens, Rembert A. Duine, Bert Koopmans
We theoretically investigate laser-induced spin transport in metallic magnetic heterostructures using an effective spin transport description that treats itinerant electrons and th…
Probing optical spin-currents using THz spin-waves in noncollinear magnetic bilayers
Tom Lichtenberg, Maarten Beens, Menno H. Jansen +2
Optically induced spin currents have proven to be useful in spintronics applications, allowing for sub-ps all-optical control of magnetization. However, the mechanism responsible f…
- model for local and nonlocal spin dynamics in laser-excited magnetic heterostructures
Maarten Beens, Rembert A. Duine, Bert Koopmans
We discuss a joint microscopic theory for the laser-induced magnetization dynamics and spin transport in magnetic heterostructures based on the - interaction. Angular momentu…
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…
Magnons versus electrons in thermal spin transport through metallic interfaces
Maarten Beens, Joseph P. Heremans, Yaroslav Tserkovnyak +1
We develop a theory for spin transport in magnetic metals that treats the contribution of magnons and electrons on equal footing. As an application we consider thermally-driven spi…
Phenomenology of current-induced skyrmion motion in antiferromagnets
Hristo Velkov, Olena Gomonay, Maarten Beens +4
We study current-driven skyrmion motion in uniaxial thin film antiferromagnets in the presence of the Dzyaloshinskii-Moriya interactions and in an external magnetic field. We pheno…
