✦ Synopsis

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 response for the field cooling susceptibility and an anomalous microwave absorption in agreement with recent experimental results
