Abstract

We have measured the transport properties of a series of underdoped YBa2Cu3O7 nanowires fabricated with widths of 100-250 nm. We observe large telegraph-like fluctuations in the resistance between the pseudogap temperature T* and the superconducting transition temperature Tc, consistent with the formation and dynamics of a domain structure such as that created by charge stripes. We also find anomalous hysteretic steps in the current-voltage characteristics well below Tc.
