Upper critical field of complex superconducting networks in the continuum limit
Abstract
We propose a simple method for calculating the superconducting upper-critical field of complex periodic two-dimensional networks in the continuum limit. Two specific lattices with space groups P4gm and C2mm are used to demonstrate this approach. We obtain the result that the ratio of the critical field of these networks to that of a uniform film is close to but larger than 2. © 1988 The American Physical Society.
