摘要

From careful four probe measurements at different magnetic fields, we deduce the critical transport current density J(c)(B) behaviour for polycrystalline Y and Gd-based superconducting samples which, on top of the characteristic Fraunhofer-like ''weak-link'' gross structure, exhibit anomalous oscillations, due to quantum interference effects in a finite number of current loops in mesoscopic networks of Josephson junctions.
