Self-organized criticality in the Bean state in YBa${}_2$Cu${}_3$O${}_{7-x}$ thin films

C. M. Aegerter, M. S. Welling, R. J. Wijngaarden

The penetration of magnetic flux into a thin film of YBa${}_2$Cu${}_3$O${}_{7-x}$ is studied when the external field is ramped slowly. In this case the flux penetrates in bursts or avala…
