    Abstract

    We report on recent experiments on electron beam lithographically prepared superconducting wire networks. We have disordered several types of networks, fit the phase boundary excellently with the J2 model and shown that there is no critical field or amount of disorder above which the phase boundary loses periodic structure. We have introduced anisotropy into the square lattice by varying the thickness of the horizontal and vertical wires. This produces an anisotropic 'phase boundary', dependent on the direction inn which the anisotropy is probed, that is in good agreement with calculations for anisotropic tight binding bands in a strong field. We have found a unique way to disorder a quasi-crystalline network and used it to demonstrate that commensurate states are directly related to the inflation properties of the network.
