Using magneto-optical visualization, individual 2
diameter antidots (circular holes) in
thin films are clearly observed.
These antidots are found to act at low temperature as very strong
pinning centres. Flux penetration takes place along the lattice
vectors of the antidot lattice. Both commensurate and
incommensurate channels are observed as well as hopping between
channels, in agreement with numerical simulations. Surprisingly,
even for these large (
antidots the trapped
flux is in agreement with previous theoretical work for small
(
antidots.
