Cover Story: Magnetic skyrmions are nanometric swirling magnetization structures with unique properties, including topological protection and particle-like dynamics. Several concepts for future spintronic devices have recently been presented in which skyrmions are key ingredients. In addition to the established ability to displace skyrmions with spin-polarized currents, a technological challenge consists in attaining control over their position. This simulation study shows that preferential skyrmion sites can be generated by introducing thickness modulations in the form of small “pockets” in thin-film elements. By inserting several such pockets, skyrmions could be arranged in regular arrays that would otherwise not form, thereby opening possible pathways for new types of magnetic metamaterials.

Since the octahedral high-spin iron(II) complex has the 5T2g ground term, the spin-orbit coupling should be considered in magnetic analysis; however, such treatment is rarely seen in recent papers, although the symmetry-sensitive property is of inter...
