Low frequency resistance fluctuations in films of high temperature superconductors

OSTI ID:6360019
Low frequency voltage fluctuations in thin films of YBa/sub 2/Cu/sub 3/O/sub 7-x/ at and above the superconducting transition have a spectral density S/sub v/(f) proportional to /bar V//sup 2//f, where /bar V/ is the average voltage across the film and f is the frequency. The value of S/sub v/(f)//bar V//sup 2/ decreases markedly as the microstructure of the films is improved. In contrast to classic superconductors, the noise at the resistive transition does not arise from equilibrium temperature fluctuations. 9 refs., 4 figs.
