Strain Engineering of Magnetic Anisotropy in Epitaxial Films of Cobalt Ferrite
Hiroshige Onoda, Hiroaki Sukegawa, Jun-ichiro Inoue +1
Perpendicular magnetic anisotropy (PMA) energy up to MJ m is demonstrated in this study by inducing large lattice-distortion exceeding 3% at room…
Spin reorientation in tetragonally distorted spinel oxide NiCoO epitaxial films
Hiroki Koizumi, Ikumi Suzuki, Daisuke Kan +4
We experimentally investigated the magnetic properties of NiCoO epitaxial films known to be conductive oxides with perpendicular magnetic anisotropy (PMA) at room temperatu…
Electrically controlled superconducting states at the heterointerface SrTiO/LaAlO
Keiji Yada, Seiichiro Onari, Yukio Tanaka +1
We study the symmetry of Cooper pair in a two-dimensional Hubbard model with the Rashba-type spin-orbit interaction as a minimal model of electron gas generated at a heterointerfac…
Spin polarization control through resonant states in an Fe/GaAs Schottky barrier
S. Honda, H. Itoh, J. Inoue +5
Spin polarization of the tunnel conductivity has been studied for Fe/GaAs junctions with Schottky barriers. It is shown that band matching of resonant interface states within the S…
Intrinsic spin Hall effect in graphene: Numerical calculations in a multi-orbital mode
Seiichiro Onari, Yasuhito Ishikawa, Hiroshi Kontani +1
We study the spin Hall effect (SHE) in graphene using a realistic multi-orbital tight-binding model that includes the atomic spin-orbit interaction. The SHE is found to be induced…
Giant Orbital Hall Effect in Transition Metals: Origin of Large Spin and Anomalous Hall Effects
H. Kontani, T. Tanaka, D. S. Hirashima +2
In transition metals and their compounds, the orbital degrees of freedom gives rise to an orbital current, in addition to the ordinary spin and charge currents. We reveal that cons…
