We analyze spin-dependent carrier dynamics due to incoherent electron–phonon scattering, which is commonly referred to as Elliott–Yafet (EY) spin-relaxation mechanism. For this mechanism one usually distinguishes two contributions: (1) from the s

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

We review a recently introduced simple model that describes magnetization dynamics in a system consisting of localized and itinerant carriers which are coupled by an antiferromagnetic exchange interaction. By also introducing a Stoner-like mean-field

We study the heat-induced magnetization dynamics in a toy model of a ferrimagnetic alloy, which includes localized spins antiferromagnetically coupled to an itinerant carrier system with a Stoner gap. We determine the one-particle spin-density matrix

We calculate lifetimes due to electron-electron scattering in a 2D Rashba band structure and study the influence of the substrate screening. A comparison with measurements on the quantum-well system Bi/Cu(111) is presented.

We present a microscopic calculation of magnetization damping for a magnetic "toy model." The magnetic system consists of itinerant carriers coupled antiferromagnetically to a dispersionless band of localized spins, and the magnetization damping is d

Using time- and angle-resolved two-photon photoemission spectroscopy, we investigate the energy- and momentum-dependent ultrafast electron dynamics in the Rashba spin-split quantum-well nanofilm Bi/Cu(111). We find an expected increase of electron li

Motivated by the recent controversy about the importance of spin-flip scattering for ultrafast demagnetization in ferromagnets, we study the spin-dependent electron dynamics based on a dynamical Elliott-Yafet mechanism. The key improvement to earlier
