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…
Element-Specific Study of Magnetic Anisotropy and Hardening in SmCoCu Thin Films
Georgia Gkouzia, Damian Günzing, Ruiwen Xie +10
This work investigates the effect of copper substitution on the magnetic properties of SmCo thin films synthesized by molecular beam epitaxy. A series of thin films with vary…
Local magnetic and geometric structure in Mn-doped La(Fe,Si)13
Benedikt Eggert, Johanna Lill, Damian Günzing +11
Magnetic cooling has the potential to replace conventional gas compression refrigeration. Materials such as La(Fe,Si) exhibit a sizeable first-order magnetocaloric effect, a…
Formation of Core-Shell Precipitates in off-stochiometric Ni-Mn-Sn Heusler alloys probed through the induced Sn-moment
Benedikt Eggert, Aslı Çakır, Damian Günzing +7
The Shell-ferromagnetic effect originates from the segregation process in off-stochiometric Ni-Mn-based Heusler. In this work, we investigate the precipitation process of L2-or…
A multi-stage, first-order phase transition in LaFe11.8Si1.2: interplay between the structural, magnetic and electronic degrees of freedom
K. P. Skokov, A. Y. Karpenkov, D. Y. Karpenkov +11
Alloys with a first-order magnetic transition are central to solid-state refrigeration technology, sensors and actuators, or spintronic devices. The discontinuous nature of the tra…
A Rate Model of Electron Populations for Non-linear High-Fluence X-ray Absorption Near-Edge Spectra
Robin Y. Engel, Markus Scholz, Jan O. Schunck +1
Absorbing a focused, femtosecond X-ray pulse from a Free-Electron Laser (FEL) can lead to extreme electronic excitations in solids. This excitation drives changes of the electronic…
