We study {ital I}{minus}{ital V} characteristics of periodic square Nb wire networks as a function of temperature in a transverse magnetic field, with a focus on three fillings 2/5, 1/2, and 0.618 that represent very different levels of incommensurability. For all three fillings, a scaling behavior of {ital I}{minus}{ital V} characteristics is found, suggesting a finite temperature continuous superconducting phase transition. The low-temperature {ital I}{minus}{ital V} characteristics are found… 
Magnetic-flux periodic response of nanoperforated ultrathin superconducting films
We have patterned ultrathin $\mathrm{Bi}∕\mathrm{Sb}$ films with a hexagonal array of nanoscale holes. These regular perforations result in a phase-sensitive periodic response to an applied magnetic
Superconducting transition in wire network under spatially modulated magnetic field
Abstract Superconducting wire network subjected to a uniform and a checkerboard-patterned magnetic field is investigated. The checkerboard field is created by an array of ferromagnetic dots placed on
Critical behaviors of triangular Josephson junction arrays in a magnetic field
Abstract The critical properties of a vortex-solid-melting transition in triangular Josephson junction arrays (JJA's) exposed to a magnetic field are studied with a focus on the fillings f =1/2, 2/5,
Phase transitions in Josephson junction arrays in a weak magnetic field
Based on the resistively shunted junction dynamics, we numerically investigate the superconducting phase transitions of two-dimensional Josephson junction arrays exposed to a dilute external field
Superconducting Transitions in Wire Network under Spatially Modulated Magnetic Field(Condensed matter: electronic structure and electrical, magnetic, and optical properties)
Superconducting wire network subjected to a uniform and a checkerboard-patterned magnetic field is investigated. The checkerboard field is created by an array of ferromagnetic dots placed on top of
Zero-temperature superconducting transition in frustrated Josephson-junction arrays
The critical behavior of zero-temperature superconducting transitions which can occur in disordered two-dimensional Josephson-junction arrays are investigated by Monte Carlo calculation of
Two-step superconducting-to-normal transitions in frustrated triangular Josephson-junction arrays
Abstract Current–voltage characteristics measurements suggest that the superconducting-to-normal transition in triangular Josephson-junction arrays with the frustration index f  = 1/4 and 1/3, which
Superconducting transitions in frustrated Josephson-junction arrays on a dice lattice
Abstract Transport measurements were carried out on dice Josephson-junction arrays with the frustration index f  = 1/3 and 1/2 which possess, within the limit of the XY model, an accidental
Modulation of superconductivity by a magnetic template in Nb/BaFe12O19 hybrids
Inhomogeneous magnetic fields generated by the BaFe12O19 ferromagnetic substrate create a magnetic template for superconducting condensate in the Nb/BaFe12O19 hybrids. Depending on the field and

TLDR
Transport measurements on superconducting Nb films with diluted triangular arrays (honeycomb and kagomé) of holes suggest that even in these specified periodic hole arrays with very large interstitial regions, the low field fine structures are determined by the connectivity of the nanostructures.
