Boltzmann-Bloch Equation Approach to the Theory of the Optical Inter- and Intraband Response in Noble Metals
Robert Lemke, Matthias Rössle, Holger Lange +2
In this paper we introduce momentum-resolved metal Boltzmann-Bloch equations (MBBE) for the combined description of electronic intra- and interband processes in noble metals. This…

Accelerating the laser-induced phase transition in nanostructured FeRh via plasmonic absorption
Maximilian Mattern, Jan-Etienne Pudell, Jon Ander Arregi +5
By ultrafast x-ray diffraction we show that the laser-induced magnetostructural phase transition in FeRh nanoislands proceeds faster and more complete than in continuous films. We…

Speed limits of the laser-induced phase transition in FeRh
Maximilian Mattern, Jasmin Jarecki, Jon Ander Arregi +3
We use ultrafast x-ray diffraction (UXRD) and the polar time-resolved magneto-optical Kerr effect (tr-MOKE) to study the laser-induced metamagnetic phase transition in two FeRh fil…
