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…
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…
Ultrafast X-ray imaging of the light-induced phase transition in VO2
Allan S. Johnson, Daniel Pérez-Salinas, Khalid M. Siddiqui +26
Using light to control transient phases in quantum materials is an emerging route to engineer new properties and functionality, with both thermal and non-thermal phases observed ou…
Mapping nanoscale charge states and phase domains with quantitative hyperspectral coherent diffractive imaging spectroscopy
Allan S. Johnson, Jordi Valls Conesa, Luciana Vidas +7
The critical properties of functional materials and nanoscale devices often originate from the coexistence of different thermodynamic phases and / or oxidization states, but sample…
Laser-induced ultrafast demagnetization and perpendicular magnetic anisotropy reduction in a CoTb thin film with stripe domains
M. Hennes, A. Merhe, X. Liu +15
We use time-resolved x-ray resonant magnetic scattering (tr-XRMS) at the Co M- and Tb O-edges to study ultrafast demagnetization in an amorphous CoTb allo…
In-situ single-shot diffractive fluence mapping for X-ray free-electron laser pulses
Michael Schneider, Christian M. Günther, Bastian Pfau +7
Free-electron lasers (FEL) in the extreme ultraviolet (XUV) and X-ray regime opened up the possibility for experiments at high power densities, in particular allowing for fluence-d…
Field-free deterministic ultra fast creation of skyrmions by spin orbit torques
Felix Büttner, Ivan Lemesh, Michael Schneider +10
Magnetic skyrmions are currently the most promising option to realize current-driven magnetic shift registers. A variety of concepts to create skyrmions were proposed and demonstra…
Nanoscale spectroscopic imaging of phase separation in a correlated material by resonant X-ray holography
Luciana Vidas, Christian M. Günther, Timothy A. Miller +8
Nanoscale phase coexistence and inhomogeneity are ubiquitous in correlated electron materials, existing in doped Mott insulators, manganites, and high-temperature superconductors.…
