Abstract

We present a systematic investigation of the antiferromagnetic ordering and structural distortion for the series of Ba(Fe_1-xRu_x) ₂As₂ compounds (0≤x≤0.246). Neutron and x-ray diffraction measurements demonstrate that, unlike for the electron-doped compounds, the structural and magnetic transitions remain coincident in temperature. Both the magnetic and structural transitions are gradually suppressed with increased Ru concentration and coexist with superconductivity. For samples that are superconducting, we find strong competition between superconductivity, the antiferromagnetic ordering, and the structural distortion.
