Outline of Final Research Achievements

We fabricated monodirectional nanowires of the hybrid structure of ultra-thin Ge and heavy metals, utilizing the unique surface structure of Ge(110). This nanowire consists of ultrathin Ge sheet at the surface and the metal atoms incorporated in the subsurface region. Since the ultrathin Ge layer is known to host an enhanced spin-orbit coupling, this nanowire is useful in the application to the spintronics devices. In order to understand the spin-related interaction between ultrathin Ge layer and the subsurface metals, we performed basic studies using model systems. We especially focused on the interface of the well-defined monolayer materials and magnetic heavy atoms. We have found that, even at the weakly-interacting interface such as h-BN-Co and graphene-LSMO interfaces, spin-related interaction is significant. We demonstrated the induction of the perpendicular magnetic anisotropy (PMA) on magnetic atoms or spin polarization in monolayer materials at the interface.
