Rapid heat assisted polarization reversal in ferroelectric thin films
Rekikua Alemayehu, Steffen Zeuschner, Alexander von Reppert +3
We demonstrate that switching of ferroelectric thin-films sandwiched between metallic electrodes can be controlled by laser-assisted heating, reminiscent of heat-assisted magnetic…

Non-thermal electrons open the non-equilibrium pathway of the phase transition in FeRh
Maximilian Mattern, Steffen Peer Zeuschner, Matthias Rössle +3
We use ultrafast x-ray diffraction to study non-equilibrium pathways of the phase transition in FeRh parametrized by the structural response. By increasing the pump-pulse duration…

Unveiling the nanomorphology of HfN thin films by ultrafast reciprocal space mapping
Steffen Peer Zeuschner, Jan-Etienne Pudell, Maximilian Mattern +5
Hafnium Nitride (HfN) is a promising and very robust alternative to gold for applications of nanoscale metals. Details of the nanomorphology related to variations in strain states…
