We study the effect of dipolar interactions on a magnetic striped monolayer
with a microscopic unit cell of square symmetry, and
of size spins.
Even if the aspect ratio
is very large,
an in-plane shape anisotropy is always negligible, except if Ny
is fairly small
. In-plane domains are not possible,
except for values of the dipolar coupling larger than the domain
wall energy.
