Abstract

We present results of AC and DC magnetic moment measurements on a Pb(50 nm)/Cu(10 nm) bilayer film with a triangular antidot lattice of spacing 866 nm and diameter 350 nm. The sharp peaking of matching anomalies in the AC and DC magnetization curves indicates a proximity coupling of the Pb and Cu layers, which is also supported by an asymmetric splitting of matching peaks in AC moment data. This work shows superconducting wire network behavior can be created and controlled in a patterned bilayer film without the complex fabrication of a Josephson tunnel junction array, or very thin superconducting wires of diameter≈coherence length.
