Phonon-dominated energy transport in purely metallic heterostructures
M. Herzog, A. von Reppert, J. -E. Pudell +5
We use ultrafast x-ray diffraction to quantify the transport of energy in laser-excited nanoscale Au/Ni bilayers. Electron transport and efficient electron-phonon coupling in Ni co…
Full spatiotemporal control of laser-excited periodic surface deformations
J. -E. Pudell, M. Sander, R. Bauer +3
We demonstrate full control of acoustic and thermal periodic deformations at solid surfaces down to sub-nanosecond time scales and few-micrometer length scales via independent vari…
Tracking picosecond strain pulses in heterostructures that exhibit giant magnetostriction
S. P. Zeuschner T. Parpiiev, T. Pezeril, A. Hillion +8
We combine ultrafast X-ray diffraction (UXRD) and time-resolved Magneto-Optical Kerr Effect (MOKE) measurements to monitor the strain pulses in laser-excited TbFe2/Nb heterostructu…
Ultrafast negative thermal expansion driven by spin-disorder
J. Pudell, A. von Reppert, D. Schick +5
We measure the transient strain profile in a nanoscale multilayer system composed of Yttrium, Holmium and Niobium after laser excitation using ultrafast X-ray diffraction. The stra…
Inhibition of the photoinduced structural phase transition in the excitonic insulator TaNiSe
Selene Mor, Marc Herzog, Johannes Noack +7
Femtosecond time-resolved mid-infrared reflectivity is used to investigate the electron and phonon dynamics occurring at the direct band gap of the excitonic insulator TaNiSe$_…
Layer specific observation of slow thermal equilibration in ultrathin metallic nanostructures by femtosecond x-ray diffraction
J. Pudell, A. Maznev, M. Herzog +5
Ultrafast heat transport in nanoscale metal multilayers is of great interest in the context of optically-induced demagnetization, remagnetization and switching. We investigate the…
