Emerging Spin-Related Phenomena in the Non-Centrosymmetric Artificial Superlattice

Various spin-relatedphenomena, such as chiral texture formation, spin-orbit torque, andRashba-induced magnetic anisotropy, have been important issues in spintronicsfield. Those phenomena are known to be observable in a bilayer structurecomposed of a ferromagnet and a heavy metal thin films with strong spin-orbitcoupling. In addition, relevant orbital hybridization is also crucial factor.Therefore, researches are limited with few material cases, which has strongspin-orbit coupling, large Berry curvature in a band, and good spintransparency. In this talk, I will introduce a new concept of a materialsystem, namely, a non-centrosymmetric artificial superlattice. I will presentthat several artificial superlattices that show large spinorbit torque, and Dzyaloshinksii-Moriya interaction. Non-centrosymmetricartificial superlattices will be a new class of material design for spinorbitronic devices.
