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.}, pages = {S349--S350}, title = {Phase Diagram of the Two-dimensional 16-band d-p Model for Iron-based Superconductors}, volume = {470}, year = {2010} }
