- Title
Influence of degradation on the spectrum of voltage fluctuations in thick films of high-temperature superconductors.

- Abstract
The noise parameters of high-temperature superconductors (yttrium barium cuprites) have been studied before and after degradation. The samples were thick films—10.5 mm × 5.5 mm × 8 µm—fabricated by magnetron sputtering on a ZrO substrate. A model is proposed for the onset of voltage fluctuations. The results of the measurements confirm that the observed noise spectrum is caused by fluctuations in the resistivity.
