摘要：

In order to analyze the diamagnetic properties of sintered granular superconductors, a circuital model consisting of a network of identical inductances (L0) and Josephson junctions is developed. In particular, the case of sufficiently high values of the maximum Josephson currents (I(j)), such that L0I(j) >> PHI0, is considered. Neglecting thermal activation processes, the process of irreversible penetration of flux quanta is studied numerically. A critical state model follows.
