A Rate Model of Electron Populations for Non-linear High-Fluence X-ray Absorption Near-Edge Spectra
Robin Y. Engel, Markus Scholz, Jan O. Schunck +1
Absorbing a focused, femtosecond X-ray pulse from a Free-Electron Laser (FEL) can lead to extreme electronic excitations in solids. This excitation drives changes of the electronic…
Electron Dynamics at High-Energy Densities in Nickel from Non-linear Resonant X-ray Absorption Spectra
Robin Y. Engel, Oliver Alexander, Kaan Atak +40
The pulse intensity from X-ray free-electron lasers (FELs) can create extreme excitation densities in solids, entering the regime of non-linear X-ray-matter interactions. We show L…
Photon shot-noise limited transient absorption soft X-ray spectroscopy at the European XFEL
Loïc Le Guyader, Andrea Eschenlohr, Martin Beye +61
Femtosecond transient soft X-ray Absorption Spectroscopy (XAS) is a very promising technique that can be employed at X-ray Free Electron Lasers (FELs) to investigate out-of-equilib…
The interplay of local electron correlations and ultrafast spin dynamics in fcc Ni
Tobias Lojewski, Mohamed F. Elhanoty, Loïc Le Guyader +48
The complex electronic structure of metallic ferromagnets is determined by a balance between exchange interaction, electron hopping leading to band formation, and local Coulomb rep…
X-ray detection of ultrashort spin current pulses in synthetic antiferromagnets
C. Stamm, C. Murer, M. S. Wörnle +8
We explore the ultrafast generation of spin currents in magnetic multilayer samples by applying fs laser pulses to one layer and measuring the magnetic response in the other layer…
X-ray spectroscopy of current-induced spin-orbit torques and spin accumulation in Pt/3d transition metal bilayers
C. Stamm, C. Murer, Y. Acremann +10
An electric current flowing in Pt, a material with strong spin-orbit coupling, leads to spins accumulating at the interfaces by virtue of the spin Hall effect and interfacial charg…
Magnetic properties of metal-organic coordination networks based on 3d transition metal atoms
María Blanco-Rey, Ane Sarasola, Corneliu Nistor +8
The magnetic anisotropy and exchange coupling between spins localized at the positions of 3d transition metal atoms forming two-dimensional metal-organic coordination networks (MOC…
Time- and spatially-resolved magnetization dynamics driven by spin-orbit torques
Manuel Baumgartner, Kevin Garello, Johannes Mendil +11
Current-induced spin-orbit torques (SOTs) represent one of the most effective ways to manipulate the magnetization in spintronic devices. The orthogonal torque-magnetization geomet…
Magneto-Optical Detection of the Spin Hall Effect in Pt and W Thin Films
Christian Stamm, Christoph Murer, Marco Berritta +4
Here we report the measurement of the interfacial spin accumulation induced by the spin Hall effect in Pt and W thin films using magneto-optical Kerr microscopy. We show that the K…
Role of critical spin fluctuations in ultrafast demagnetization of transition-metal rare-earth alloys
V. Lopez-Flores, N. Bergeard, V. Halte +6
Ultrafast magnetization dynamics induced by femtosecond laser pulses have been measured in ferrimagnetic Co0.8Gd0.2, Co.74Tb.26 and Co.86Tb.14 alloys. Using element sensitivity of…
Hot electron driven enhancement of spin-lattice coupling in 4f ferromagnets observed by femtosecond x-ray magnetic circular dichroism
Marko Wietstruk, Alexey Melnikov, Christian Stamm +7
Due to an error this article has been annouced as a new article instead of a corrected version of article 1010.1374.
Hot electron driven enhancement of spin-lattice coupling in 4f ferromagnets observed by femtosecond x-ray magnetic circular dichroism
Marko Wietstruk, Alexey Melnikov, Christian Stamm +7
Femtosecond x-ray magnetic circular dichroism was used to study the time-dependent magnetic moment of 4 fs electrons in the ferromagnets Gd and Tb, which are known for their differ…
