Abstract

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 N_y is fairly small . In-plane domains are not possible, except for values of the dipolar coupling larger than the domain wall energy.
