State-resolved ultrafast charge and spin dynamics in [Co/Pd] multilayers
Loïc Le Guyader, Daniel J. Higley, Matteo Pancaldi +17
We use transient absorption spectroscopy with circularly polarized x-rays to detect laser-excited hole states below the Fermi level and compare their dynamics with that of unoccupi…
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…
Using photoelectron spectroscopy to measure resonant inelastic X-ray scattering: A computational investigation
Daniel J. Higley, Hirohito Ogasawara, Sioan Zohar +1
Resonant inelastic X-ray scattering (RIXS) has become an important scientific tool. Nonetheless, conventional high-resolution RIXS measurements (<100 meV), especially in the soft x…
Ultrafast perturbation of magnetic domains by optical pumping in a ferromagnetic multilayer
Dmitriy Zusin, Ezio Iacocca, Loïc Le Guyader +23
Ultrafast optical pumping of spatially nonuniform magnetic textures is known to induce far-from-equilibrium spin transport effects. Here, we use ultrafast x-ray diffraction with un…
Distinguishing Local and non-Local Demagnetization in Ferromagnetic FePt Nanoparticles
Patrick W. Granitzka, Alexander H. Reid, Jerome Hurst +21
Time-resolved coherent X-ray diffraction is used to measure the spatially resolved magnetization structure within FePt nanoparticles during laser-induced ultrafast demagnetization.…
Ultrafast X-Ray Induced Changes of the Electronic and Magnetic Response of Solids Due to Valence Electron Redistribution
Daniel J. Higley, Alex H. Reid, Zhao Chen +13
We report a novel mechanism, consisting of redistribution of valence electrons near the Fermi level, during interactions of intense femtosecond X-ray pulses with a Co/Pd multilayer…
