Abstract
In this contribution, we present a simple and effective procedure to determ ine the average critical current of a tridimensional disordered Josephson j unction array (3D-DJJA). Using a contactless configuration we evaluate the average critical current and the typical width of the distribution through the analysis of the isothermal susceptibility response to the excitation fi eld amplitude. chi (AC)(h). A 3D-DJJA fabricated from granular Nb is used t o illustrate the method. (C) 2001 Elsevier Science B.V. All rights reserved .
