Onset of the transitional flux-avalanche regime in bulk NbTi controlled by the thermal boundary conductance
Irina Abaloszewa, Victor V. Chabanenko, Aleksander Abaloszew
Thermomagnetic avalanches in type-II superconductors occur in two qualitatively different regimes, electromagnetically controlled in thin films and thermally limited in bulk sample…
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…
Numerical modeling of the influence of randomly macroscopic inhomogeneities on the magnetic induction and temperature dynamics of a high-T superconducting slab
C. Romero-Salazar, P. L. Valdés-Negrin, C. E. Ávila-Crisóstomo +4
In this study we perform numerical calculations of the spatial and time variation of the magnetic induction, current density and temperature in an infinite superconducting slab wit…
