摘要：

We have fabricated and measured the transport properties of a series of YBa2Cu3O7-delta nanowires ranging from 100 to 200 nm in width. In all samples we observe hysteretic steps in the current-voltage characteristics below the superconducting transition temperature T-c and switching fluctuations in the resistance as the temperature is varied well above T-c. The data may be evidence for the formation of a domain structure such as charge stripes. (C) 2003 Elsevier Science B.V. All rights reserved.
