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
The purpose of this paper is to explain the unusual isotope coefficients of cuprates by considering the influence of a pseudogap and phononic and electronic interactions in weak-coupling limit. Exact analytic expressions of the isotope exponent (a) for the s-and d-wave pairing symmetry are derived.
