Picosecond localization dynamics following ultrafast nanoscale magnetic switching
Daniel Metternich, Michael Schneider, Giuseppe Mercurio +28
Ultrashort laser pulses provide the fastest known way to switch magnetic order. Such excitation commonly creates nanometer-scale domains, even after homogeneous illumination when t…
High frame rate RIXS spectroscopy using a JUNGFRAU detector with an iLGAD sensor
Nuno Duarte, Loïc Le Guyader, Viktoria Hinger +17
Resonant inelastic X-ray scattering (RIXS) is a powerful photon-in, photon-out spectroscopy technique for probing electronic, magnetic, and lattice excitations in matter. Time-reso…
Photo-generated charge-transfer excitons in NiO revealed by ultrafast time-resolved resonant inelastic x-ray scattering
Giacomo Merzoni, Leonardo Martinelli, Sergii Parchenko +32
Strong electronic correlation can lead to insulating behavior and to the opening of large optical gaps, even in materials with partly filled valence shells. Although the non-equili…
Ultrafast decoupling of polarization and strain in ferroelectric BaTiO
Le Phuong Hoang, David Pesquera, Gerard N. Hinsley +20
A fundamental understanding of the interplay between lattice structure, polarization and electrons is pivotal to the optical control of ferroelectrics. The interaction between ligh…
Non-equilibrium self-assembly of spin-wave solitons in FePt nanoparticles
D. Turenne, A. Yaroslavtsev, X. Wang +36
Magnetic nanoparticles such as FePt in the L10-phase are the bedrock of our current data storage technology. As the grains become smaller to keep up with technological demands, the…
Ultrafast X-Ray Induced Changes of the Electronic and Magnetic Response of Solids Due to Valence Electron Redistribution
Daniel J. Higley, Alex H. Reid, Zhao Chen +13
We report a novel mechanism, consisting of redistribution of valence electrons near the Fermi level, during interactions of intense femtosecond X-ray pulses with a Co/Pd multilayer…
