Abstract
Embodiments may provide the realization of strong Dzyaloshinskii-Moriya Interaction (DMI) and perpendicular magnetic anisotropy (PMA) induced by chemisorbed species on a ferromagnetic layer. For example, in an embodiment, an apparatus for generating a Dzyaloshinskii-Moriya interaction may comprise a ferromagnet comprising a single layer or multi-layers of materials made of metal, oxide or other types of magnetic films, and a substance chemisorbed on a surface of the ferromagnet to induce the Dzyaloshinskii-Moriya interaction or the perpendicular magnetic anisotropy at the interface between chemisorbed species and ferromagnet. These induced effects may be used to manipulate spin textures such as switching of domain wall chirality and writing/deleting of magnetic skyrmions, which are relevant for spintronics, magneto-ionics as well as gas sensing.
