Evaluating the critical current magnitude and distribution width of tridimensional Josephson junction arrays

W.A.C Passos, U.R de Oliveira, W.A Ortiz

Abstract

In this contribution we present a simple and effective procedure to determine the average critical current of a tridimensional disordered Josephson junction 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 field amplitude, chiAC(h). A 3D-DJJA fabricated from granular Nb is used to illustrate the method.
