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…
Phase separation in the non-equilibrium Verwey transition in magnetite
Francesco Randi, Ignacio Vergara, Fabio Novelli +9
We present equilibrium and out-of-equilibrium studies of the Verwey transition in magnetite. In the equilibrium optical conductivity, we find a step-like change at the phase transi…
Microwave soft x-ray microscopy for nanoscale magnetization dynamics in the 5-10 GHz frequency range
Stefano Bonetti, Roopali Kukreja, Zhao Chen +11
We present a scanning transmission x-ray microscopy setup combined with a novel microwave synchronization scheme in order to study high frequency magnetization dynamics at synchrot…
Direct observation and imaging of a spin-wave soliton with like symmetry
S. Bonetti, R. Kukreja, Z. Chen +12
The prediction and realization of magnetic excitations driven by electrical currents via the spin transfer torque effect, enables novel magnetic nano-devices where spin-waves can b…
Correlation-driven insulator-metal transition in near-ideal vanadium dioxide films
A. X. Gray, J. Jeong, N. P. Aetukuri +17
We use polarization- and temperature-dependent x-ray absorption spectroscopy, in combination with photoelectron microscopy, x-ray diffraction and electronic transport measurements,…
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…
