Avalanches and Self-Organized Criticality in Superconductors
Rinke J. Wijngaarden, Marco S. Welling, Christof M. Aegerter +1
We review the use of superconductors as a playground for the experimental study of front roughening and avalanches. Using the magneto-optical technique, the spatial distribution of…
Dynamic roughening of the magnetic flux landscape in YBaCuO
C. M. Aegerter, M. S. Welling, R. J. Wijngaarden
We study the magnetic flux landscape in YBaCuO thin films as a two dimensional rough surface. The vortex density in the superconductor forms a self-affine structure…
Self-organized criticality induced by quenched disorder: experiments on flux avalanches in NbH films
M. S. Welling, C. M. Aegerter, R. J. Wijngaarden
We present an experimental study of the influence of quenched disorder on the distribution of flux avalanches in type-II superconductors. In the presence of much quenched disorder,…
Dendritic flux avalanches and nonlocal electrodynamics in thin superconducting films
Igor S. Aranson, Alex Gurevich, Marco S. Welling +4
We present numerical and analytical studies of coupled nonlinear Maxwell and thermal diffusion equations which describe nonisothermal dendritic flux penetration in superconducting…
Self-organized criticality in the Bean state in YBaCuO thin films
C. M. Aegerter, M. S. Welling, R. J. Wijngaarden
The penetration of magnetic flux into a thin film of YBaCuO is studied when the external field is ramped slowly. In this case the flux penetrates in bursts or avala…
