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…
Diffractive imaging of a molecular rotational wavepacket with femtosecond Megaelectronvolt electron pulses
Jie Yang, Markus Guehr, Theodore Vecchione +20
Imaging changes in molecular geometries on their natural femtosecond timescale with sub-Angstrom spatial precision is one of the critical challenges in the chemical sciences, since…
Generation of high-frequency strain waves during femtosecond demagnetization of Fe/MgO films
T. Henighan, M. Trigo, S. Bonetti +22
We use femtosecond time-resolved hard x-ray scattering to detect coherent acoustic phonons excited during ultrafast laser demagnetization of bcc Fe films. We determine the lattice…
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,…
