Abstract
It is shown that in antiferromagnetic open or closed corrals of magnetic adatoms grown on surfaces, the attachment of a single extra adatom anywhere in the corral impacts on the geometrical topology of the nanosystem and generates complex magnetic structures when a magnetic field is applied or a magnetic coupling to a ferromagnetic substrate exists. The spin configuration of the corral can be tuned to a nonplanar state or a planar noncollinear or ferrimagnetic state by adjusting its number of sites, the location of the extra adatom, or the strength of the coupling to the ferromagnetic substrate. This shows the possibility to generate nontrivial magnetic textures with atom-by-atom engineering anywhere in the corral and not only at the edges.
