内容記述タイプ Abstract
内容記述 The electronic state of the Fe2As2 plane in iron-based superconductors is investigated on the basis of the two-dimensional 16-band d –p model. Using the random phase approximation for the on-site Coulomb interaction between Fe d electrons, we obtain the phase diagram including the magnetic ordered states and the superconductivity. It is found that the s±-wave superconductivity, where the gap functions have different signs between the electron pockets and the hole pockets, is realized near the incommensurate magnetic ordered phase with q~(π,π). The absolute values of the gap functions on the Fermi surfaces are almost isotropic but largely depend on the energy bands.
