Ultrafast Dissipative Localization of Electronic Energy in AuPt Superlattices
C. Walz, M. Mattern, J. -E. Pudell +15
Controlling the spatial distribution of absorbed optical energy is central to nanoscale photothermal chemistry, plasmonics, and ultrafast materials control. Here, we show that a me…
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…
Rapid heat assisted polarization reversal in ferroelectric thin films
Rekikua Alemayehu, Steffen Zeuschner, Alexander von Reppert +3
We demonstrate that switching of ferroelectric thin-films sandwiched between metallic electrodes can be controlled by laser-assisted heating, reminiscent of heat-assisted magnetic…
Large strain contribution to the laser-driven magnetization response of magnetostrictive TbFe
C. Walz, F. -C. Weber, S. -P. Zeuschner +3
We investigate strain-induced contributions to the transient polar magneto-optical Kerr effect response in laser-excited terfenol. The tr-MOKE signals obtained from TbFe film…
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…
Non-thermal electrons open the non-equilibrium pathway of the phase transition in FeRh
Maximilian Mattern, Steffen Peer Zeuschner, Matthias Rössle +3
We use ultrafast x-ray diffraction to study non-equilibrium pathways of the phase transition in FeRh parametrized by the structural response. By increasing the pump-pulse duration…
Concepts and use cases for picosecond ultrasonics with x-rays
Maximilian Mattern, Alexander von Reppert, Steffen Peer Zeuschner +3
This review discusses picosecond ultrasonics experiments using ultrashort hard x-ray probe pulses to extract the transient strain response of laser-excited nanoscopic structures fr…
Standing spin wave excitation in Bi:YIG films via temperature induced anisotropy changes and magnetoacoustic coupling
Steffen Peer Zeuschner, Xi-Guang Wang, Marwan Deb +6
Based on micromagnetic simulations and experimental observations of the magnetization and lattice dynamics following the direct optical excitation of the magnetic insulator Bi:YIG…
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…
