Experimental evidence of dominant ultrafast diffusive energy transport by hot electrons in Cu
Jasmin Jarecki, Lisa Mehner, Maximilian Mattern +15
When the dimensions of structures shrink to the order of the inelastic mean free path of the energy-carrying quasi-particles, the character of energy transport changes from diffusi…
Dark-Field X-ray Microscopy for 2D and 3D imaging of Microstructural Dynamics at the European X-ray Free Electron Laser
Sara J. Irvine, Kento Katagiri, Trygve M. Ræder +26
Dark field X-ray microscopy (DXFM) can visualize microstructural distortions in bulk crystals. Using the femtosecond X-ray pulses generated by X-ray free-electron lasers (XFEL), DF…
Unveiling the nanomorphology of HfN thin films by ultrafast reciprocal space mapping
Steffen Peer Zeuschner, Jan-Etienne Pudell, Maximilian Mattern +5
Hafnium Nitride (HfN) is a promising and very robust alternative to gold for applications of nanoscale metals. Details of the nanomorphology related to variations in strain states…
Controlling effective field contributions to laser-induced magnetization precession by heterostructure design
Jasmin Jarecki, Maximilian Mattern, Fried-Conrad Weber +6
Nanoscale heterostructure design can control laser-induced heat dissipation and strain propagation as well as their efficiency for driving magnetization precession. We use insulati…
Accelerating the laser-induced phase transition in nanostructured FeRh via plasmonic absorption
Maximilian Mattern, Jan-Etienne Pudell, Jon Ander Arregi +5
By ultrafast x-ray diffraction we show that the laser-induced magnetostructural phase transition in FeRh nanoislands proceeds faster and more complete than in continuous films. We…
