Wohlleben effect in a model granular high TC superconductor

We discuss a phenomenological model for granular Bi-2212 superconductors which consists of a network of Josephson junctions with a random distribution of φ-junctions. We calculate the field cooling and zero field cooling susceptibility using dynamical Langevin simulations. We obtain a paramagnetic r...

Description
Summary:We discuss a phenomenological model for granular Bi-2212 superconductors which consists of a network of Josephson junctions with a random distribution of φ-junctions. We calculate the field cooling and zero field cooling susceptibility using dynamical Langevin simulations. We obtain a paramagnetic response for the field cooling susceptibility and an anomalous microwave absorption in agreement with recent experimental results
