Abstract
Voltage noise has been measured with DC currents at temperatures near Tc in c-axis oriented DyBaCuO thin films. Two regimes of noise are observed as a function of magnetic field. For H<5kG, there are reproducible, microstructure-dependent "fingerprints" of variations of noise with field. These can be interpreted as collective vortex rearrangements between quasi-equilibrium configurations within the pinning potential produced by the granularity of the films.
