Abstract:

We study the effect of dipolar interactions on a magnetic striped monolayer with a microscopic unit cell of square symmetry, and of size \(({N_x}X{N_y})\) spins. Even if the aspect ratio r=N x /N y is very large, an in-plane shape anisotropy is always negligible, except if Ny is fairly small (N y <40). In-plane domains are not possible, except for values of the dipolar coupling larger than the domain wall energy.
