    We performed an XUV-pump XUV-probe experiment on warm dense hydrogen with sub-picosecond time resolution at the XUV free-electron laser facility (FLASH) at DESY (Hamburg). Ultra-fast impulsive electron heating was initiated by a ≤ 300 fs short photon pulse at 92 eV energy. A second XUV pulse probed jitter-free the heated sample via x-ray scattering at variable time delays. We showed that the...

    We report on multiphoton processes involving inner-shell electrons of solid Fe with very intense and ultra-short hard x-ray free-electron laser (XFEL) pulses. The experiment was carried out at the CXI end-station of the Linac Coherent Light Source by means of the high energy resolution x-ray emission technique. The XFEL beam of ~10^12 photons/pulse and pulse energy in the range of 1-4 mJ was...

  4. 65. Electron spin resonance study in the chiral ferrimagnet Cu2OSeO3 using pulsed magnetic fields up to 64 T and terahertz free electron laser

    The recent discovery of skyrmions in Cu2OSeO3 has established a new platform to create and manipulate skyrmionic spin textures. We use high-field electron spin resonance (ESR) spectroscopy combining a terahertz free electron laser and pulsed magnetic fields up to 64 T to probe and quantify its microscopic spin-spin interactions. Besides providing direct access to the long-wavelength Goldstone...
