Abstract

We report measurements of the normal-superconducting phase boundary T_c (H) for a series of square wire networks with a range of ratios for the wire widths in the two perpendicular directions. We find indirect evidence for anisotropic localization of the superconducting order parameter through the vanishing of structure in T_c(H) at rational fields, and direct evidence in the field-dependent lowering of the resistive transition for the narrow wires relative to the wide wires. This represents experimental evidence for anisotropic localization in a periodic system in a homogeneous field as originally predicted by Aubry and André.
