Spin waves excited by hard x-ray transient gratings

Peter R. Miedaner, Alexei A. Maznev, Mykola Biednov +49

Recent progress in ultrafast x-ray sources helped establish x-rays as an important tool for probing lattice and magnetic dynamics initiated by femtosecond optical pulses. Here, we…

Time-domain extreme ultraviolet diffuse scattering spectroscopy of nanoscale surface phonons

F. Capotondi, A. Maznev, F. Bencivenga +18

We report the observation of dynamic fringe patterns in the diffuse scattering of extreme ultraviolet light from surfaces, following femtosecond optical excitation. At each point o…

Nanoscale transient polarization gratings

Laura Foglia, Björn Wehinger, Giovanni Perosa +24

We present the generation of transient polarization gratings at the nanoscale, achieved using a tailored accelerator configuration of the FERMI free electron laser. We demonstrate…

Characterizing the Nonequilibrium Response of FeRh Thin Films using Time-Domain Thermoreflectance (TDTR)

Renee M. Harton, Alejandro Ceballos, Vivek Unikandanunni +4

Time-Domain Thermoreflectance (TDTR) characterization of FeRh throughout its first-order antiferromagnetic (AF) to ferromagnetic (FM) transition shows that the transient reflectanc…
