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…
Impact ionization dynamics in small band-gap 2D materials from a coherent phonon mechanism
Stephan Michael, Hans Christian Schneider
We study theoretically the role of carrier multiplication due to impact ionization after an ultrafast optical excitation in a model system of a quasi-two dimensional material with…
Particle-in-cell simulation of ultrafast hot-carrier transport in Fe/Au-heterostructures
Dennis M. Nenno, Bärbel Rethfeld, Hans Christian Schneider
We describe a theoretical approach for spin-polarized hot-electron transport, as it occurs after excitation by ultrafast optical pulses in heterostructures formed by ferromagnetic…
Off-resonant all-optical switching dynamics in a ferromagnetic model system
Christiane Scholl, Svenja Vollmar, Hans Christian Schneider
We present a theoretical study of the the effects of off-resonant polarized optical fields on a ferromagnetic model system. We determine the light-induced dynamics of itinerant car…
Ultrafast spin-lattice relaxation in ferromagnets including effective spin-orbit fields
Kai Leckron, Svenja Vollmar, Hans Christian Schneider
We investigate ultrafast demagnetization due to electron-phonon interaction in a model band-ferromagnet. We show that the microscopic mechanism behind the spin dynamics due to elec…
Ultrafast Hole-Spin Dynamics in Optically Excited Bulk GaA
Michael Krauss, David J. Hilton, Hans Christian Schneider
We present experimental and theoretical results on hole-spin dynamics in bulk GaAs after ultrafast optical excitation. The experimental differential transmission are compared with…
