We discuss a phenomenological model for granular Bi-2212 superconductors which consists of a network of Josephson junctions with a random distribution of r-junctions. We calculate the field cooling and zero field cooling susceptibility using dinamical Langevin simulations. We obtain a paramagnetic r
Interaction between spontaneous current loops (orbital magnetic moments) induced by weak links with negative coupling energies (n-junctions) can cause paramagnetism of granular high-temperature superconductors. For a not very small concentration of n-junctions p interaction between current loops yie
