Abstract

Pronounced random telegraph signals have been observed in voltages measured across current-biased thin-film YBa₂Cu₃O_7-δ superconducting bridges containing laser-processed channels for easy vortex motion. The appearance of two-level and three-level telegraph noise in bridges with single and double laser-written channels, respectively, is interpreted as experimental evidence for intermittent channeled vortex flow in current induced dissipative state in type-II superconductors.
