Vortex avalanches and self organized criticality in superconducting niobium

E. Altshuler, T. H. Johansen, Y. Paltiel +6

In 1993 Tang proposed [1] that vortex avalanches should produce a self organized critical state in superconductors, but conclusive evidence for this has heretofore been lacking. In…
