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 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 switching in granular FePt layers promoted by near-field laser enhancement
Patrick W. Granitzka, Emmanuelle Jal, Loïc Le Guyader +20
Light-matter interaction at the nanoscale in magnetic materials is a topic of intense research in view of potential applications in next-generation high-density magnetic recording.…
Beyond a phenomenological description of magnetostriction
A. H. Reid, X. Shen, P. Maldonado +28
We use ultrafast x-ray and electron diffraction to disentangle spin-lattice coupling of granular FePt in the time domain. The reduced dimensionality of single-crystalline FePt nano…
Femtosecond X-ray magnetic circular dichroism absorption spectroscopy at an X-ray free electron laser
Daniel J. Higley, Konstantin Hirsch, Georgi L. Dakovski +25
X-ray magnetic circular dichroism spectroscopy using an X-ray free electron laser is demonstrated with spectra over the Fe L-edges. This new ultrafast time-resolved capabil…
Creation of X-Ray Transparency of Matter by Stimulated Elastic Forward Scattering
Joachim Stöhr, Andreas Scherz
X-ray absorption by matter has long been described by the famous Beer-Lambert law. Here we show how this fundamental law needs to be modified for high-intensity coherent x-ray puls…
X-Ray Detection of Transient Magnetic Moments Induced by a Spin Current in Cu
R. Kukreja, S. Bonetti, Z. Chen +7
We have used a MHz lock-in x-ray spectro-microscopy technique to directly detect changes of magnetic moments in Cu due to spin injection from an adjacent Co layer. The elemental an…
