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 films. It …

We develop a fast numerical procedure for the analysis of nonlinear and nonlocal
electrodynamics of type-II superconducting films in transverse magnetic fields coupled with …

We propose a mechanism responsible for the abrupt vanishing of the dendritic flux instability
found in many superconducting films when an increasing magnetic field is applied. The …

Using magneto-optical imaging the phenomenon of dendritic flux penetration in
superconducting films was studied. Flux dendrites were abruptly formed in a 300-nm-thick …

Magneto-optical imaging reveal that below 10 K the penetration of magnetic flux in MgB 2
films is dominated by dendritic structures abruptly formed in response to an applied field …

Magneto-optical imaging is used to visualize vortex avalanches in Mg B 2 films at 4 K.
Avalanches ranging from 50 to 50 000 vortices were detected. The size distribution function …

Magneto-optical imaging reveals that in superconducting films of MgB2 a pulse of transport
current creates avalanche-like flux dynamics where highly branching dendritic patterns are …

We report a mechanism of nonisothermal dendritic flux penetration in superconducting films.
Our numerical and analytical analysis of coupled nonlinear Maxwell and thermal diffusion …

Vortex avalanches are known to occur in MgB 2 films within a certain range of temperatures
and magnetic fields. These events, resulting from a thermomagnetic instability, were first …

Flux distributions in thin superconducting NbN films placed in a perpendicular magnetic field
have been studied using magneto-optical imaging. Below 5.5 K the flux penetrates in the …
