Using light to control transient phases in quantum materials is an emerging route engineer new properties and functionality, with both thermal non-thermal observed out of equilibrium. Transient are expected be heterogeneous, either through photo-generated domain growth or by generating topological defects, this impacts the dynamics system. However, nanoscale heterogeneity has not been directly observed. Here we use time- spectrally resolved coherent X-ray imaging track prototypical induced...
We show, through visible-range Mueller polarimetry, as well numerical simulations, that the depolarization in a homogeneous turbid medium consisting of submicron spherical particles follows parabolic law with path-length traveled by light medium. This result is full agreement phenomenological theory fluctuating within framework differential matrix formalism. further found standard deviations elementary polarization properties depend linearly on concentration particles. These findings are...
Magnetic nanoparticles such as FePt in the L1 0 phase are bedrock of our current data storage technology. As grains become smaller to keep up with technological demands, superparamagnetic limit calls for materials higher magnetocrystalline anisotropy. This, turn, reduces magnetic exchange length just a few nanometers, enabling structures be induced within nanoparticles. Here, we describe existence spin-wave solitons, dynamic localized bound states excitations, We show time-resolved x-ray...
A change of orbital state alters the coupling between ions and their surroundings drastically. Orbital excitations are hence key to understand control interaction ions. Rare-earth elements with strong magneto-crystalline anisotropy (MCA) important ingredients for magnetic devices. Thus, localized 4
The advent of X-ray free-electron lasers (XFELs) has revolutionized fundamental science, from atomic to condensed matter physics, chemistry biology, giving researchers access X-rays with unprecedented brightness, coherence and pulse duration. All XFEL facilities built until recently provided pulses at a relatively low repetition rate, limited data statistics. Here, results the first megahertz-repetition-rate scattering experiments Spectroscopy Coherent Scattering (SCS) instrument European...
In recent years, femtosecond extreme-ultraviolet (XUV) and x-ray pulses from free-electron lasers have developed into important probes to monitor processes dynamics in matter on femtosecond-time angstrom-length scales. With the rapid progress of versatile ultrafast spectroscopy techniques more sophisticated data analysis tools, accurate single-pulse information arrival time, duration, shape probing XUV becomes essential. Here, we demonstrate that can be converted terahertz electromagnetic...
