Susceptibility in Granular Superconductors : Theory and Experiment

A phenomenological theory to describe the electromagnetic properties of granular superconductors, based on known bulk superconductors expressions and conventional Josephson’s junctions tunneling currents, is presented and successfully used to fit distinct experimental results for the magnetic susceptibility χ as a function of the temperature and the applied magnetic field of rather different sa...

Vortex jamming in superconductors and granular rheology

We demonstrate that a highly frustrated anisotropic Josephson junction array (JJA) on a square lattice exhibits a zero-temperature jamming transition, which shares much in common with those in granular systems. Anisotropy of the Josephson couplings along the horizontal and vertical directions plays roles similar to normal load or density in granular systems. We studied numerically static and dy...

ns-Tc correlations in granular superconductors.

Following a short discussion of the granular model for an inhomogeneous superconductor, we review the Uemura and Homes correlations and show how both follow in two limits of a simple granular superconductor model. Definite expressions are given for the almost universal coefficients appearing in these relationships in terms of known constants.

Magnetic field induced polarization effects in intrinsically granular superconductors

Based on the previously suggested model of nanoscale dislocations induced Josephson junctions and their arrays, we study the magnetic field induced electric polarization effects in intrinsically granular superconductors. In addition to a new phenomenon of chemomagnetoelectricity, the model predicts also a few other interesting effects, including charge analogues of Meissner paramagnetism (at lo...

Phase-coherence transition in granular superconductors with π junctions

We study the three-dimensional XY-spin glass as a model for the resistive behavior of granular superconductors containing a random distribution of π junctions, as in high-Tc superconducting materials with d-wave symmetry. The π junctions leads to quenched in circulating currents (chiralities) and to a chiral-glass state at low temperatures, even in the absence of an external magnetic field. Dyn...
