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…
Ultrafast demagnetization of iron induced by optical vs terahertz pulses
A. L. Chekhov, Y. Behovits, J. J. F. Heitz +7
We study ultrafast magnetization quenching of ferromagnetic iron following excitation by an optical vs a terahertz pump pulse. While the optical pump (photon energy of 3.1 eV) indu…
Optical control of 4f orbital state in rare-earth metals
N. Thielemann-Kühn, T. Amrhein, W. Bronsch +28
A change of orbital state alters the coupling between ions and their surroundings drastically. Orbital excitations are hence key to understand and control interaction of ions. Rare…
