title: Electronic structure and magnetic anisotropy of a constrained Fe chain in an electric field.
abstract: The electronic structure and magnetic anisotropy were studied for a constrained iron chain in an electric field by means of the first-principles approach. The electron induced by the electric field was found to occupy mainly the extended s-like orbitals which is well hybridized with the d(3z(2)-r(2)) localized orbital. The magnetic anisotropy was observed to decrease with the number of induced electrons and to depend on the magnetization direction. The magnetization perpendicular both to the chain and the electric field modifies the electron dispersion relation to be asymmetrical, which implies an expectation of variable transport property with both the external electric and magnetic fields.
