Spin+Non-Equilibrium: Ultrafast non-equilibrium and transport (B03)

点击翻译按钮获取中文摘要

The project aims at understanding of far-from-equilibrium dynamics in ferromagnetic metals and ferromagnet-metal multilayers, in particular, magnetization dynamics and spin-dependent transport as they occur after ultrashort-pulse excitations and mainly on ultra-fast timescales. The theory part of this project investigates electron-magnon interactions and combines Boltzmann transport equations, stochastic methods, and macroscopic approaches to cover electronic spin dynamics in metallic systems on all relevant energy scales. Experimentally, electronic dynamics far from equilibrium are studied using a novel method based on the ultrafast magneto-optical Kerr effect with depth resolution.
