Size of flux jumps in superconducting films
D. V. Shantsev, A. V. Bobyl, Y. M. Galperin +2
Magneto-optical imaging is used to visualize vortex avalanches in MgB2 films at 4K. Avalanches ranging from 50 to 50000 vortices were detected. The size distribution function has a…

Avalanche-driven fractal flux distributions in NbN superconducting films
I. A. Rudnev, D. V. Shantsev, T. H. Johansen +1
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 th…
