Magnetic properties of weakly coupled superconducting grains

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

We investigate the thermodynamic properties of weakly coupled superconducting grains in a magnetic field. Starting from the mean field approximation, we treat the induced field and the nonlinearities self-consistently. Close to but slightly belowT c (H), the order parameter, the magnetization and the variance of the induced-field distribution. Recent experiments on high-T c materials are consistent with these predictions.
