Sub-10 nm Quantification of Spin and Orbital Magnetic Moment Across the Metamagnetic Phase Transition in FeRh Using EMCD
Jan Hajduček, Veronica Leccese, Ján Rusz +9
Electron magnetic circular dichroism (EMCD) in transmission electron microscopy (TEM) enables element-specific measurement of spin and orbital magnetic moments, analogous to X-ray…
Ultrafast X-ray sonography reveals the spatial heterogeneity of the laser-induced magneto-structural phase transition in FeRh
Maximilian Mattern, Angel Rodriguez-Fernandez, Roman Shayduk +13
Phase transitions are governed by both intrinsic and extrinsic heterogeneities, yet capturing their spatio-temporal dynamics remains a challenge. While ultrafast techniques track p…
Dislocation-Driven Nucleation Type Switching Across Repeated Ultrafast Magnetostructural Phase Transition
Jan Hajduček, Antoine Andrieux, Jon Ander Arregi +6
Controlling magnetic order on ultrafast timescales, driven by spintronic and recording applications, is one of the main directions of current research in magnetism. Despite major a…
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…
Mie-enhanced micro-focused Brillouin light scattering with wavevector resolution
Jakub Krčma, Ondřej Wojewoda, Martin Hrtoň +4
Magnons, the quanta of spin waves, are magnetic excitations of matter spanning through the entire crystal's Brillouin zone and covering a wide range of frequencies ranging from sub…
Achieving Different Stoichiometries and Morphologies in Vapor Phase Deposition of Inorganic Halide Perovskites: Single or Dual Precursor Sources?
Tomáš Musálek, Petr Liška, Amedeo Morsa +6
Inorganic halide perovskites have become attractive for many optoelectronic applications due to their outstanding properties. While chemical synthesis techniques have been successf…
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…
