Near complete laser-induced modulation of the ferromagnetic-antiferromagnetic phase fraction in FeRh films
Alexis Pecheux, Robin Salvatore, Laura Thevenard +6
With its huge entropy change and a strong interplay between magnetic order, structural and electrical properties, the first-order antiferromagnetic/ferromagnetic phase transition i…

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…

Dimensional Crossover of Microscopic Magnetic Metasurfaces for Magnetic Field Amplification
N. Lejeune, E. Fourneau, A. Barrera +8
Transformation optics applied to low frequency magnetic systems has been recently implemented to design magnetic field concentrators and cloaks with superior performance. Although…
