Nanoscale Confinement Enhances Ultrafast Demagnetization

Yoav William Windsor, Tobias Lojewski, Moumita Kundu +21

Nanoscale miniaturization has revolutionized the field of spintronics by enabling exponential growth in areal bit density. A similar leap is also expected in device speeds through…

Analysis of long-lived effects in high-repetition-rate stroboscopic transient X-ray absorption experiments on thin films

Tobias Lojewski, Loïc Le Guyader, Naman Agarwal +41

Time-resolved X-ray absorption spectroscopy (tr-XAS) has been shown to be a versatile measurement technique for investigating non-equilibrium dynamics. Novel X-ray free electron la…

Femtosecond spin-state switching dynamics of spin-crossover molecules condensed in thin films

Lea Kämmerer, Gérald Kämmerer, Manuel Gruber +22

The photoinduced switching of Fe(II)-based spin-crossover complexes from singlet to quintet takes place at ultrafast time scales. This a priori spin-forbidden transition triggered…

Photo-induced charge-transfer renormalization in NiO

Tobias Lojewski, Denis Golez, Katharina Ollefs +21

Photo-doped states in strongly correlated charge transfer insulators are characterized by - and - interactions and the resulting intertwined dynamics of charge excitati…

Photon shot-noise limited transient absorption soft X-ray spectroscopy at the European XFEL

Loïc Le Guyader, Andrea Eschenlohr, Martin Beye +61

Femtosecond transient soft X-ray Absorption Spectroscopy (XAS) is a very promising technique that can be employed at X-ray Free Electron Lasers (FELs) to investigate out-of-equilib…

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…
