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…

Dynamic interfacial effects in ultrathin ferromagnetic bilayers
Anulekha De, Christopher Seibel, Sanjay Ashok +7
We investigate the magnetization dynamics of an ultrathin Co (1.5 nm) /Py (1.5 nm) bilayer system from femtosecond (fs) to nanosecond (ns) timescales. Magnetization dynamics in the…

Ultrafast electron-phonon scattering in antiferromagnetic Dirac semimetals
Marius Weber, Kai Leckron, Libor Å mejkal +3
Topological antiferromagnetic systems, which exhibit anisotropic band structures combined with complex relativistic spin structures in momentum space, have shown strong magnetoresi…
