Magnetic skyrmions are topologically protected spin textures typical of chiral magnets characterized by a special kind of exchange interaction known as Dzyaloshinkii-Moriya interaction (DMI). In the last years growing interest has been addressed to the study of these topological defects both from a fundamental point of view and for its several technological applications like for instance their usage as information carriers. Great attention has been also given to skyrmion nucleation, stability and motion in confined magnetic systems under the influence of a spin-current. Recently, the effect of confinement has been studied in the presence of spin-polarized current, but there are not yet studies focusing on the skyrmion motion driven by SHE in constrained geometries.
