Abstract

We present the results of a Langevin dynamic simulation of an inductively coupled Josephson-junction array in the absence of π junctions. The magnetic susceptibility (4πχ) under field-cooled conditions becomes positive in certain range of applied field (f) in antithesis to the Meissner effect, whereas the zero-field cooled susceptibility is negative for all values of f. The results are discussed in the light of recent experiments showing a paramagnetic Meissner effect in certain granular superconductors.
