Femtosecond charge and spin dynamics in CoPt alloys

Martin Pavelka, Simon Marotzke, Ru-Pan Wang +19

The use of advanced X-ray sources plays a key role in the study of dynamic processes in magnetically ordered materials. The progress in X-ray free electron lasers enables the direc…

How to Measure and Model Light-Induced Spin Transfer

Sinéad A. Ryan, Mohamed F. Elhanoty, Anya Grafov +13

Femtosecond laser light can transfer spin angular momentum between magnetic subspecies that exhibit hybridized valence bands within an alloy or compound, and represents the fastest…

How quantum selection rules influence the magneto-optical effects of driven, ultrafast magnetization dynamics

Mohamed F. Elhanoty, Olle Eriksson, Chin Shen Ong +1

Ultrafast magnetization dynamics driven by ultrashort pump lasers is typically explained by changes in electronic populations and scattering pathways of excited conduction electron…

Optically controlling the competition between spin flips and intersite spin transfer in a Heusler half-metal on sub-100 fs timescales

Sinéad A. Ryan, Peter C. Johnsen, Mohamed F. Elhanoty +10

The direct manipulation of spins via light may provide a path toward ultrafast energy-efficient devices. However, distinguishing the microscopic processes that can occur during ult…

The interplay of local electron correlations and ultrafast spin dynamics in fcc Ni

Tobias Lojewski, Mohamed F. Elhanoty, Loïc Le Guyader +48

The complex electronic structure of metallic ferromagnets is determined by a balance between exchange interaction, electron hopping leading to band formation, and local Coulomb rep…

Element selective ultrafast magnetization dynamics of hybrid Stoner-Heisenberg magnets

Mohamed F. Elhanoty, Olle Eriksson, Ronny Knut +2

Stoner and Heisenberg excitations in magnetic materials are inherently different. The former involves an effective reduction of the exchange splitting, whereas the latter comprises…
