Magnon-mediated terahertz spin transport in metallic Gd|Pt stacks
Oliver Gueckstock, Tim Amrhein, Beatrice Andres +11
We study femtosecond spin transport in a Gd|Pt stack induced by a laser pulse. Remarkably, the dynamics of the spin current from Gd to Pt suggests that its dominant driving force i…
Local work-function manipulation by external optical stimulation
Jan Böhnke, Beatrice Andres, Larissa Boie +4
Strongly differing static dipole moments of the trans and cis isomers of photochromic azobenzene allow for optical switching the work function of azobenzene-functionalized self-ass…
Strong Momentum-Dependent Electron-Magnon Renormalization of a Surface Resonance on Iron
Beatrice Andres, Martin Weinelt, Hubert Ebert +3
The coupling of fermionic quasiparticles to magnons is essential for a wide range of processes, from ultrafast magnetization dynamics in ferromagnets to Cooper pairing in supercond…
The role of spin-lattice coupling for ultrafast magnetization changes in rare earth metals
Beatrice Andres, Sang Eun Lee, Martin Weinelt
By comparing femtosecond laser-pulse-induced spin dynamics in the surface state of the rare earth metals Gd and Tb we show that the spin polarization of the valence states in both…
