Ultrafast electron-phonon scattering in antiferromagnetic Dirac semimetals
Marius Weber, Kai Leckron, Libor Šmejkal +3
Topological antiferromagnetic systems, which exhibit anisotropic band structures combined with complex relativistic spin structures in momentum space, have shown strong magnetoresi…
Competing signatures of intersite and interlayer spin transfer in the ultrafast magnetization dynamics
Simon Häuser, Sebastian T. Weber, Christopher Seibel +10
Optically driven intersite and interlayer spin transfer are individually known as the fastest processes for manipulating the spin order of magnetic materials on the sub 100 fs time…
Interplay of electron-magnon scattering and spin-orbit induced electronic spin-flip scattering in a two-band Stoner model
Félix Dusabirane, Kai Leckron, Baerbel Rethfeld +1
This paper presents a theoretical investigation of electron-magnon scattering processes in the ultrafast demagnetization in itinerant ferromagnets. In the framework of a ferromagne…
Effect of iron thicknesses on spin transport in a Fe/Au bilayer system
J. Briones, M. Weber, B. Stadtmüller +2
This paper is concerned with a theoretical analysis of the behavior of optically excited spin currents in bilayer and multilayer systems of ferromagnetic and normal metals. As the…
Ultrafast Demagnetization Dynamics Due to Electron-Electron Scattering and Its Relation to Momentum Relaxation in Ferromagnets
Svenja Vollmar, Kai Leckron, Hans Christian Schneider
We analyze theoretically the demagnetization dynamics in a ferromagnetic model system due to the interplay of spin-orbit coupling and electron-electron Coulomb scattering. We compu…
Indirect optical manipulation of the antiferromagnetic order of insulating NiO by ultrafast interfacial energy transfer
Stephan Wust, Christopher Seibel, Hendrik Meer +14
We report the ultrafast, (sub)picosecond reduction of the antiferromagnetic order of the insulating NiO thin film in a Pt/NiO bilayer. This reduction of the antiferromagnetic order…
