Anisotropic Magnetoresistance Effects in Fe, Co, Ni, Fe_4N, and Half-Metallic Ferromagnet: A Systematic Analysis
Satoshi Kokado, Masakiyo Tsunoda, Kikuo Harigaya +1
We theoretically analyze the anisotropic magnetoresistance (AMR) effects of bcc Fe (+), fcc Co (+), fcc Ni (+), FeN (-), and a half-metallic ferromagnet (-). The sign in each (…
Electron density distribution of bilayer nanographene and band structures of boron-carbon-nitride systems
Kikuo Harigaya, Hiroshi Imamura
Bilayer graphene nanoribbon with zigzag edge is investigated with the tight binding model. Two stacking structures, alpha and beta, are considered. The band splitting is seen in th…
Possible magnetic states in buckybowl molecules
Kikuo Harigaya
Possible magnetic properties are studied in the buckybowl molecules: the sumanene and a part of C_60. The Hubbard model is applied to the systems. We find that the molecular struct…
Edge States and Stacking Effects in Nanographene Systems
Kikuo Harigaya, Hiroshi Imamura, Katsunori Wakabayashi +1
Bilayer graphene nanoribbon with zigzag edge is investigated with the tight binding model. Two stacking structures, alpha and beta, are considered. The band splitting is seen in th…
