Effect of iron thicknesses on spin transport in a Fe/Au bilayer system
J. Briones, M. Weber, B. Stadtmüller +2
This paper is concerned with a theoretical analysis of the behavior of optically excited spin currents in bilayer and multilayer systems of ferromagnetic and normal metals. As the…
Fundamentals of Scanning Surface Structuring by Ultrashort Laser Pulses: From Electron Diffusion to Final Morphology
F. Nyenhuis, P. N. Terekhin, T. Menold +3
Industrial use of ultrashort-pulse surface structuring would significantly increase by an effective utilization of the average laser powers available currently. However, the unexpl…
Influence of an external electric field on the energy dissipation at the initial stage of laser ablation
S. Hirtle, P. N. Terekhin, M. Schäfer +4
A density-dependent two-temperature model is applied to describe laser excitation and the following relaxation processes of silicon in an external electric field. Two approaches on…
An adaptive model for the optical properties of excited gold
P. D. Ndione, S. T. Weber, D. O. Gericke +1
We study the temperature-dependent optical properties of gold over a broad energy spectrum covering photon energies below and above the interband threshold. We apply a semi-analyti…
Semi-implicit finite-difference method with predictor-corrector algorithm for solution of diffusion equation with nonlinear terms
V. P. Lipp, B. Rethfeld, M. E. Garcia +1
We present a finite-difference integration algorithm for solution of a system of differential equations containing a diffusion equation with nonlinear terms. The approach is based…
Driving Force of Ultrafast Magnetization Dynamics
Benedikt Y. Mueller, T. Roth, M. Cinchetti +2
Irradiating a ferromagnetic material with an ultrashort laser pulse leads to demagnetization on a femtosecond timescale. We implement Elliott-Yafet type spin-flip scattering, media…
