(a) Geometry of the nanostrips used in this work. Also shown the self-generated magnetic field lines, or vortices, (dashed arrows) entering the sample in the presence of a current bias I b and in correspondence of the four nanostrip corners. (b) Schematic representation of the streamlines of the vortex and anti-vortex current densities before annihilation, the arrows shows the vortex current density direction. (c) A SEM (scansion electron microscopy) image of sample B (w = 800 nm).
