【 摘 要 】

In this paper, we determine the magnetic field dependence of the critical current of a tridimensional disordered Josephson junction array. A contactless configuration, employing measurements of the AC-susceptibility, is used to evaluate the average critical current of an array of YBa2CU3O7-delta. The critical field necessary to switch off supercurrents through the weak links at the working temperature is also obtained. (C) 2001 Elsevier Science B.V. All rights reserved.
