Annealing-enhanced spin-orbit effects in non-centrosymmetric superconducting NbRe films
Zahra Makhdoumi Kakhaki, Yuriy Yerin, Francesco Avitabile +5
(NbRe) is a non-centrosymmetric superconductor with a transition temperature reaching in bulk form. While bulk and si…
AC-flux-driven SQUID diode spectroscopy as a probe of current-phase relations
Yuriy Yerin, Iman Askerzade, Alexey Fedorchenko +2
The current-phase relation (CPR) of a Josephson junction encodes microscopic information on superconducting states through higher-order and fractional harmonics. However, their una…
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…
Annealing-induced grain coarsening and voltage kinks in superconducting NbRe films
Zahra Makhdoumi Kakhaki, Anton O. Pokusinskyi, Francesco Avitabile +5
NbRe, a non-centrosymmetric superconductor with a transition temperature up to 9\,K, attracts interest for its strong antisymmetric spin-orbit coupling and suitabili…
DC-driven separation of fractional flux quanta in two-band superconductors
Anton O. Pokusinskyi, Oleksandr V. Dobrovolskiy
Two-band superconductors host vortices from superfluid condensates of different electron bands. These vortices carry a fractional flux quantum and attract each other, coalescing to…
Vortex ratchet effect in superconductor open nanotubes and nanopetals
Igor Bogush, Rodrigo H. de Bragança, Vladimir M. Fomin +1
Advancements in the fabrication of superconducting 3D nanostructures and the creation of artificial pinning sites pave the way to novel applications and enhancement of nanosensors,…
