Cascade dynamics of thermomagnetic avalanches in superconducting films with holes
(2015)
The submicrosecond dynamics of thermomagnetic avalanches in superconducting films with nonconducting holes (antidots) is considered. When such an avalanche reaches a hole, it is quickly filled with magnetic flux, and often ...
Oscillatory regimes of the thermomagnetic instability in superconducting films
(2016)
The stability of superconducting films with respect to oscillatory precursor modes for thermomagnetic avalanches is investigated theoretically. The results for the onset threshold show that previous treatments of nonoscillatory ...
Scaling Behavior of Quasi-One-Dimensional Vortex Avalanches in Superconducting Films
(2020-03-27)
Scaling behaviour of dynamically driven vortex avalanches in superconducting YBa2Cu3O7−δ films deposited on tilted crystalline substrates has been observed using quantitative magneto-optical imaging. Two films with different ...
Nucleation and propagation of thermomagnetic avalanches in thin-film superconductors (Review Article)
(2018)
Stability of the vortex matter—magnetic flux lines penetrating into the material—in type-II superconductor films is crucially important for their application. If some vortices get detached from pinning centres, the energy ...
Dendritic flux avalanches in a superconducting MgB2 tape
(2017)
Tapes of MgB2 with high critical current have a significant technological potential, but can experience operational breakdown due to thermomagnetic instabilities. Such events are routinely registered by magnetisation ...
