Crystal structure effects on vortex dynamics in superconducting MgB thin films
Clemens Schmid, Anton Pokusinskyi, Markus Gruber +7
The current-driven resistive transition is central to superconducting single-photon detectors, transition-edge sensors, and fluxonic devices. Depending on sample uniformity, dimens…

Real-time detection of critical slowing-down at the superconducting phase transition
Guillermo Nava Antonio, Théo Courtois, Corentin Pfaff +5
We employ optical pump-THz probe spectroscopy to chart the ultrafast superconductivity suppression in NbN over a broad range of excitation fluences. Our measurements uncover a pron…

Exploring Co, Fe, and Ni Reference Layers for Single-Pulse All-Optical Reversal in Ferromagnetic Spin Valves
Jun-Xiao Lin, Yann Le Guen, Julius Hohlfeld +6
We investigate the magnetization reversal process induced by a single femtosecond laser pulse in ferromagnetic spin valves by systematically comparing reference layers composed of…
