Ferromagnetic model system with spin-orbit coupling: Dynamical gap and effective spin-flip scattering

Autor: Hans Christian Schneider, Kai Leckron

Publikováno v: Journal of Magnetism and Magnetic Materials. 471:482-485

We investigate ultrafast magnetization dynamics due to electron-phonon interaction in a ferromagnetic Rashba model, which includes spin-orbit coupling and a Stoner mean-field splitting. By computing the reduced spin-density matrix including explicitl

Exchange scattering on ultrafast timescales in a ferromagnetic two-sublattice system

Autor: Kai Leckron, Alexander Baral, Hans Christian Schneider

Publikováno v: Applied Physics Letters. 120:102407

We investigate ultrafast spin dynamics due to exchange, electron–phonon and Elliott–Yafet spin-flip scattering in a model with a simple band structure and ferromagnetically coupled electronic sublattices (or more generally, subsystems). We show t

Spin-dependent electronic scattering dynamics in a ferromagnetic model system: Numerical Aspects

Autor: Kai Leckron, Hans Christian Schneider

Publikováno v: Ultrafast Bandgap Photonics III.

We investigate ultrafast magnetization dynamics due to electron-phonon interaction in a ferromagnetic model sys- tem including spin-orbit coupling. By computing the reduced spin-density matrix and Boltzmann-type scattering integrals, we identify the

Ultrafast spin-lattice relaxation in ferromagnets including spin-orbit fields

Autor: Kai Leckron, Svenja Vollmar, Hans Christian Schneider

Publikováno v: Physical Review B. 96

We investigate ultrafast demagnetization due to electron-phonon interaction in a model band ferromagnet. We show that the microscopic mechanism behind the spin dynamics due to electron-phonon interaction is the interplay of scattering and the precess
