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…

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…

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…

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…
