Vortex pinning and rectification effect in a nanostructured superconducting film with a square array of antidot triplets |
(color online) (a) Normalized critical current density as a function of applied magnetic field (in units of the first matching field H1 in the A–D array) for the two array geometries of holes. (b) The contour plots of the simulated ground state vortex configurations at the first, second, and third matching fields for different arrays of A–D (S1, S2)) and the array A–B–D (S3). |
