Terahertz switching of antiferromagnetic order by Néel spin-orbit torques
Yannic Behovits, Alexander L. Chekhov, Amon Ruge +13
Ultrafast electric manipulation of magnetic order in solids is critical for the development of future terahertz data processing. A fascinating concept for such high-speed operation…
Femtosecond signatures of optically induced magnons before ultrafast demagnetization
Reza Rouzegar, Oliver Franke, Gal Lemut +8
Optically induced demagnetization of 3d metallic ferromagnets proceeds as fast as ~100 fs and is a crucial prerequisite for spintronic applications, such as ultrafast magnetization…
Ultrafast electron heating as the dominant driving force of photoinduced terahertz spin currents
Reza Rouzegar, Pilar Jimenez-Cavero, Oliver Gueckstock +9
Ultrafast spintronics strongly relies on the generation, transport, manipulation and detection of terahertz spin currents (TSCs). In F|HM stacks consisting of a ferromagnetic layer…
Femtosecond photocurrents by the Dresselhaus bulk spin-galvanic effect in an inversion-asymmetric ferromagnet
Junwei Tong, Zdenek Kaspar, Afnan Alostaz +18
We study ultrafast photocurrents in thin films of a model ferromagnetic metal with broken bulk inversion symmetry, the half-metallic Heusler compound NiMnSb, following excitation w…
Terahertz time-domain signatures of the inverse Edelstein effect in topological-insulator|ferromagnet heterostructures
Genaro Bierhance, Chihun In, Enzo Rongione +14
Three-dimensional topological insulators possess topologically protected surface states with spin-momentum locking, which enable spin-charge-current interconversion (SCI) by the in…
Hallmarks of terahertz magnon currents in an antiferromagnetic insulator
Hongsong Qiu, Oliver Franke, Yuanzhe Tian +11
The efficient transport of spin angular momentum is expected to play a crucial role in future spintronic devices, which potentially operate at frequencies reaching the terahertz ra…
Magnon-mediated terahertz spin transport in metallic Gd|Pt stacks
Oliver Gueckstock, Tim Amrhein, Beatrice Andres +11
We study femtosecond spin transport in a Gd|Pt stack induced by a laser pulse. Remarkably, the dynamics of the spin current from Gd to Pt suggests that its dominant driving force i…
