Description

We have produced very small (200 x 200 x 60 nm) superconducting microbridges in which the bridges are made from a normal metal. The critical-current--vs--temperature curves can be fit very well by theoretical curves calculated using the microscopic equations of Usadel; this fitting procedure gives reduced lengths for the bridges. The intrinsic response time of these structures has been determined, and the dependence of this time on both the reduced lengths and on the temperature is found to be in agreement with predictions based on time-dependent Ginzburg-Landau theory
