      abstract     = {The magnetic order of the localized Eu2+ spins in optimally
                      doped Eu(Fe1−xIrx)2As2 (x=0.12) with superconducting
                      transition temperature TSC=22 K was investigated by
                      single-crystal neutron diffraction. The Eu2+ moments were
                      found to be ferromagnetically aligned along the c direction
                      with an ordered moment of 7.0(1) μB well below the magnetic
                      phase transition temperature TC=17 K. No evidence of the
                      tetragonal-to-orthorhombic structural phase transition was
                      found in this compound within the experimental uncertainty,
                      in which the spin-density-wave (SDW) order of the Fe
                      sublattice is supposed to be completely suppressed and the
                      superconductivity gets fully developed. The ferromagnetic
                      ground state of the Eu2+ spins in Eu(Fe0.88Ir0.12)2As2 was
                      supported by the first-principles density functional
                      calculation. In addition, comparison of the electronic
                      structure calculations between Eu(Fe0.875Ir0.125)2As2 and
                      the parent compound EuFe2As2 indicates stronger
                      hybridization and more expanded bandwidth due to the Ir
                      substitution, which together with the introduction of
                      electrons might work against the Fe-SDW in favor of the
                      superconductivity.},
