Spin Interaction and Control
In our group, we investigate the fundamental connections between spin waves, spin-polarized electrons and photons, combining the three research directions of magnonics, spintronics and photonics. This research is driven by the demand for new concepts, technologies and materials for information processing. On one side, electronics are reaching their physical limit of operation speed due to waste heat generation. On the other side, photonics lacks fast, electronic control on small length scales. Spin waves, being the fundamental dynamic excitations of ferromagnets with frequencies in the gigahertz to terahertz regime, offer the unique opportunity to merge the best aspects of spintronics and photonics opening new pathways for information processing.
Our methods cover time- and phase-resolved Brillouin light scattering microscopy (TR-µBLS), time-resolved magneto-optical Kerr microscopy (TR-µMOKE), electrical detection via the (inverse) spin Hall effect (ISHE) as well as micromagnetic simulation.
