Avalanches Injecting Flux into the Central Hole of a Superconducting MgB2 Ring
Age Andreas Falnes Olsen, Tom Henning Johansen, Daniel Shantsev +4
Magneto-optical imaging was used to observe dendritic flux avalanches connecting the outer and inner edges of a ring-shaped superconducting MgB2 film. Such avalanches create heated…

Flux Dendrites of Opposite Polarity in Superconducting MgB rings observed with magneto-optical imaging
Age Andreas Falnes Olsen, Tom Henning Johansen, Daniel Shantsev +4
Magneto-optical imaging was used to observe flux dendrites with opposite polarities simultaneously penetrate superconducting, ring-shaped MgB films. By applying a perpendicular…

Onset of dendritic flux avalanches in superconducting films
D. V. Denisov, D. V. Shantsev, Y. M. Galperin +7
We report a detailed comparison of experimental data and theoretical predictions for the dendritic flux instability, believed to be a generic behavior of type-II superconducting fi…
