Magnetically memorable inductance in superconducting multilayer resonators
R. Tyumenev, D. S. Kalashnikov, B. V. Fradkin +10
Superconductor-ferromagnet hybrid structures with tunable kinetic inductance are promising elements for neuromorphic and quantum computing circuits. We report the fabrication and m…
Effect of charge-imbalance potential relaxation on the high-frequency vortex dynamics and kinetic inductance of superconducting circuits
R. I. Kinzibaev, V. S. Stolyarov, A. S. Mel'nikov
We show that relaxation of the charge-imbalance potential plays a key role in the retarded dynamics of Abrikosov vortices in a type-II superconducting sample carrying a microwave c…
Equidistant resonance jumps in superconducting coplanar resonators driven by Abrikosov vortices
Dmitrii S. Kalashnikov, Denis Yu. Vodolazov, Ruslan I. Kinzibaev +2
Superconducting coplanar resonators are key building blocks of cryogenic microwave circuits, yet their performance in perpendicular magnetic fields is ultimately limited by Abrikos…
Superconducting properties of NbSc film deposited by magnetron co-sputtering
Paul Berezhnoy, Anna Elistratova, Zakhar Enbaev +8
The technology has been developed for synthesizing NbSc films using magnetron co-sputtering from Nb and Sc targets. The material synthesis was accompanied by structural…
Microscopic structure of the vortex cores in granular niobium: A coherent quantum puzzle
V. S. Stolyarov, V. Neverov, A. V. Krasavin +12
When macroscopic quantum condensates -- superconductors, superfluids, cold atoms and ions, polaritons etc. -- are put in rotation, a quantum vortex lattice forms inside. In homogen…
