Effective Theory of Ultrafast Skyrmion Nucleation
Rein Liefferink, Lukas Körber, Kathinka Gerlinger +3
Laser-induced ultrafast skyrmion nucleation has been experimentally demonstrated in several materials. So far, atomistic models have been used to corroborate experimental results.…
Emergent Chaos-Like Dynamics of Spin-Orbit Torque-Driven Magnetic Transitions
Lisa-Marie Kern, Kai Litzius, Victor Deinhart +12
Spin-orbit torques (SOTs) are widely used to control magnetization in nanoscale electric systems and are typically assumed to drive skyrmion nucleation and motion in a deterministi…
Coherent x-ray magnetic imaging with 5 nm resolution
Riccardo Battistelli, Daniel Metternich, Michael Schneider +13
Soft x-ray microscopy plays an important role in modern spintronics. However, the achievable resolution of most x-ray magnetic imaging experiments is above 10 nm, limiting access t…
Robust scenario for the generation of non-equilibrium topological fluctuation states
Kathinka Gerlinger, Rein Liefferink, Michael Schneider +12
The recently discovered topological fluctuation state provides a fascinating new perspective on the ultrafast emergence of topology in condensed matter systems. However, rather lit…
Pump--probe x-ray microscopy of photo-induced magnetization dynamics at MHz repetition rates
Kathinka Gerlinger, Bastian Pfau, Martin Hennecke +11
We present time-resolved scanning x-ray microscopy measurements with picosecond photo-excitation via a tailored infrared pump laser at a scanning transmission x-ray microscope. Spe…
Tailoring Optical Excitation to Control Magnetic Skyrmion Nucleation
Lisa-Marie Kern, Bastian Pfau, Michael Schneider +12
In ferromagnetic multilayers, a single laser pulse with a fluence above an optical nucleation threshold can create magnetic skyrmions, which are randomly distributed over the area…
Deterministic Generation and Guided Motion of Magnetic Skyrmions by Focused He-Ion Irradiation
L. -M. Kern, B. Pfau, V. Deinhart +17
Magnetic skyrmions are quasiparticles with non-trivial topology, envisioned to play a key role in next-generation data technology while simultaneously attracting fundamental resear…
