Abstract

Measurements on Niobium and Vanadium foils are reported, which allow to locate the sources for flux flow noise at pinning sites of the samples. The investigation of its time behavior results in a proportionality over at least two decades between the time constant of the associated autocorrelation function and the mean velocity of the flux lines. This time constant turns out to be controlled by a characteristic length, which appears to be given by the pinning structure of the sample.
