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…
Magneto-optical evidence for single-crystal-like magnetic switching of epitaxial antiferromagnetic LaFeO3 films
A. Rieche, W. Hoppe, C. Körner +11
Strained epitaxial films of the antiferromagnetic orthoferrite LaFeO3 offer a promising platform for antiferromagnetic spintronics, yet their magnetic switching behavior and domain…
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…
Atomistic spin dynamics with quantum colored noise
Fried-Conrad Weber, Felix Hartmann, Matias Bargheer +2
The accurate prediction of temperature-dependent magnetization dynamics is a fundamental challenge in computational magnetism. While Atomistic Spin Dynamics (ASD) simulations have…
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…
Coherent control of magnetization precession by double-pulse activation of effective fields from magnetoacoustics and demagnetization
M. Mattern, F. -C. Weber, D. Engel +2
We demonstrate the coherent optical control of magnetization precession in a thin Ni film by a second excitation pulse which amplifies or attenuates the precession induced by a fir…
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…
