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…
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…
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…
Preserving Metamagnetism in Self-Assembled FeRh Nanomagnets
Lucie Motyčková, Jon Ander Arregi, Michal Staňo +3
We present self-assembly routes of metamagnetic FeRh nanoisland arrays using sputter deposition processing. Controlling the growth parameters and epitaxy allows tuning the size and…
Subpicosecond metamagnetic phase transition driven by non-equilibrium electron dynamics
Federico Pressacco, Davide Sangalli, Vojtěch Uhlíř +13
Femtosecond light-induced phase transitions between different macroscopic orders provide the possibility to tune the functional properties of condensed matter on ultrafast timescal…
Laser induced phase transition in epitaxial FeRh layers studied by pump-probe valence band photoemission
Federico Pressacco, Vojtěch Uhlíř, Matteo Gatti +7
We use time-resolved X-ray photoelectron spectroscopy to probe the electronic and magnetization dynamics in FeRh films after ultrafast laser excitations. We present experimental an…

Jimmy J. Kan, Marko V. Lubarda, Keith T. Chan +4
We report on experimental and computational investigations of the domain structure of ~0.2 x 0.2 x 8 μm single-crystal Ni nanowires (NWs). The Ni NWs were grown by a thermal chemic…
Colossal magnetic phase transition asymmetry in mesoscale FeRh stripes
Vojtech Uhlir, Jon Ander Arregi, Eric E. Fullerton
Coupled order parameters in phase-transition materials can be controlled using various driving forces such as temperature, magnetic and electric field, strain, spin-polarized curre…
Photoinduced Enhancement of the Charge Density Wave Amplitude
A. Singer, S. K. K. Patel, R. Kukreja +14
Symmetry breaking and the emergence of order is one of the most fascinating phenomena in condensed matter physics. It leads to a plethora of intriguing ground states found in antif…
Phase diagram of magnetic domain walls in spin valve nano-stripes
Nicolas Rougemaille, Vojtech Uhlîr, Olivier Fruchart +3
We investigate numerically the transverse versus vortex phase diagram of head-to-head domain walls in Co/Cu/Py spin valve nano-stripes (Py: Permalloy), in which the Co layer is mos…
