- We investigate the effect of magnetostatic interactions on the magnetization reversal process of equilateral triangular rings arranged on a hexagonal lattice. Inter-ring interactions originate as rings corners host domain-walls that produce an intense dipolar field; the effect of such interactions is studied by recording hysteresis loops for different magnetic field orientations. Rings magnetic configuration is probed via magnetic force microscopy and diffraction magneto-optic Kerr effect measurements. We observe that the effect of stray fields due to domain-walls competes with that of shape anisotropy, and that the former prevails when the magnetic field orientation is parallel to rings symmetry axes.
