| The resistive response of c-axis textured YBa2Cu3O7 bridges (100 nm thick and 10 µm wide) has been studied dynamically on the nanosecond scale over a wide span of temperatures and currents. From Tc down to 75 K, dissipation is dominated by the viscosity of vortices spontaneously generated in the earth's magnetic field. For 70 K < T < 75 K, vortex ow coexists with phase-slip centers (PSCs) characteristic of one-dimensional (1-D) transport. Eventually, below about 70 K, vortex ow is inhibited while, independently, PSCs transform into normal hot spots. All these resistive modes are identified by using a different time-varying voltage consecutive to the application of a step function of the current to the bridge. |
