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.

该项目旨在了解铁磁金属和铁磁-金属多层膜中远离平衡的动力学，特别是磁化动力学和自旋相关的输运，因为它们发生在超短脉冲激发后，主要是在超快时间尺度上。该项目的理论部分研究电子-磁振子相互作用，并结合玻耳兹曼输运方程、随机方法和宏观方法来涵盖所有相关能量尺度上金属系统中的电子自旋动力学。实验上，利用一种基于深度分辨的超快磁光克尔效应的新方法，研究了远离平衡的电子动力学。
