Structural effects on the magnetic properties of elementary cubic networks of Josephson junctions

A general analytic approach to the study of structural deformation effects on the electrodynamic properties of elementary cubic networks of Josephson junctions (JJs) is presented. The undeformed network consists of twelve JJs interrupting the edges of a superconducting cubic structure. By first order perturbation analysis on the deformation parameters it is shown that, as in the unperturbed case, for well defined applied field orientations, the voltage vs. applied magnetic flux curves present a period which can be an uncommensurate multiple of the elementary flux quantum.
