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…
Spin Hall effect in Sr2RuO4 and transition metals (Nb,Ta)
T. Tanaka, H. Kontani, M. Naito +3
We study the intrinsic spin Hall conductivity (SHC) and the -orbital Hall conductivity (OHC) in metallic -electron systems based on the multiorbital tight-binding model. The…
Predominant Magnetic States in Hubbard Model on Anisotropic Triangular Lattices
Tsutomu Watanabe, Hisatoshi Yokoyama, Yukio Tanaka +1
Using an optimization variational Monte Carlo method, we study the half-filled-band Hubbard model on anisotropic triangular lattices, as a continuation of the preceding study [J. P…
Study of Intrinsic Spin Hall Effect and Orbital Hall Effect in 4d- and 5d- Transition Metals
T. Tanaka, H. Kontani, M. Naito +4
We study the intrinsic spin Hall conductivity (SHC) in various -transition metals (Ta, W, Re, Os, Ir, Pt, and Au) and 4d-transition metals (Nb, Mo, Tc, Ru, Rh, Pd, and Ag) base…
