Thermally-controlled flux avalanche dynamics in bulk NbTi superconductor
Irina Abaloszewa, Viktor V. Chabanenko, Aleksander Abaloszew
We report the first direct visualization of flux avalanche propagation dynamics in bulk superconducting NbTi, tracking individual events and measuring their velocities using high-s…
Transformation of the trapped flux in a SC disc under electromagnetic exposure
V. V. Chabanenko, I. Abaloszewa, V. F. Rusakov +6
Superconducting permanent magnets (SCs) with trapped magnetic flux are used in technical devices (motors, generators, etc.). These magnets endure repeated magnetic "shocks" during…
Properties of YBaCuO films grown by pulsed laser deposition on CeO-buffered sapphire
I. Abaloszewa, P. Gierłowski, A. Abaloszew +11
In the present work we study the growth by pulsed laser deposition of YBaCuO (YBCO) films on the r-cut sapphire substrates. To improve the matching of the lattice p…
Upper critical field and superconductor-metal transition in ultrathin niobium films
I. Zaytseva, A. Abaloszew, B. C. Camargo +2
Recent studies suggests that in disordered ultrathin films superconducting (SC) state may be intrinsically inhomogeneous. Here we investigate the nature of SC state in ultrathin Nb…
