Probing the wave-vector gap in nanoscale magnonics
Ondřej Wojewoda, Samer Kurdi, Toeno van der Sar +3
Short-wavelength spin waves are central to miniaturizing magnonic devices and to studying exchange-dominated magnetization dynamics. Yet the wave-vector range between roughly 30 an…
Depth-resolved magnetization dynamics in Fe thin films after ultrafast laser excitation
Valentin Chardonnet, Marcel Hennes, Romain Jarrier +12
We performed time-resolved x-ray resonant magnetic reflectivity measurements on a laser-excited ferromagnetic Fe thin film to simultaneously probe the transient magnetic and struct…
Anisotropic skyrmion liquid phase
Daniel Schick, Tim Matthies, Thomas Mutschler +2
The nature of the melting transition in two-dimensional systems of particles has attracted considerable research attention since the development of Kosterlitz-Thouless-Halperin-Nel…
Ultrafast X-ray sonography reveals the spatial heterogeneity of the laser-induced magneto-structural phase transition in FeRh
Maximilian Mattern, Angel Rodriguez-Fernandez, Roman Shayduk +13
Phase transitions are governed by both intrinsic and extrinsic heterogeneities, yet capturing their spatio-temporal dynamics remains a challenge. While ultrafast techniques track p…
X-ray View of Light-Induced Spin Reorientation in TmFeO: Direct Observation of a 90 Néel Vector Rotation
Somnath Jana, Ronny Knut, Dima Afanasiev +8
Using time-resolved X-ray magnetic linear dichroism in reflection, we provide a direct probe of the Néel vector dynamics in TmFeO on a ultrafast timescale. Our measurements rev…
Soft-X-ray momentum microscopy of nonlinear magnon interactions below 100-nm wavelength
Steffen Wittrock, Christopher Klose, Salvatore Perna +10
Magnons are quantised collective excitations of long-range ordered spins. At nanometre wavelengths, exchange interactions increasingly govern their dynamics, giving rise to a large…
Fluence dependent delay of Ni in an FeNi alloy supports an exchange based origin
Somnath Jana, Ronny Knut, Puloma Singh +9
The delayed demagnetization in Ni relative to Fe in the ultrafast demagnetization studies in FeNi alloy has led to two competing theoretical explanations: The Inhomogeneous Magnon…
Spectroscopic probe of ultrafast magnetization dynamics in the extreme ultraviolet spectral range
Johanna Richter, Somnath Jana, Robert Behrends +6
The development of spectroscopic techniques in the extreme ultraviolet (XUV) spectral range has significantly advanced the understanding of ultrafast interactions in magnetic syste…
Laser-driven resonant soft-X-ray scattering for probing picosecond dynamics of nanometre-scale order
Leonid Lunin, Martin Borchert, Niklas Schneider +6
X-ray scattering has been an indispensable tool in advancing our understanding of matter, from the first evidence of the crystal lattice to recent discoveries of nuclei's fastest d…
Ultrafast energy-dispersive soft-x-ray diffraction in the water window with a laser-driven source
Jasmin Jarecki, Martin Hennecke, Themistoklis Sidiropoulos +3
Time-resolved soft-x-ray-diffraction experiments give access to microscopic processes in a broad range of solid-state materials by probing ultrafast dynamics of ordering phenomena.…
Magneto-Optical Functions at the 3p resonances of Fe, Co, and Ni: Ab-initio description and experiment
F. Willems, S. Sharma, C. v. Korff Schmising +7
We present theoretical and experimental data on the magneto-optical contributions to the complex refractive index in the extreme ultraviolet (XUV) range covering the 3p resonances…
