Abstract

Neutron-diffraction and high-resolution x-ray diffraction studies find that, similar to the closely related underdoped Ba (Fe_1-x Co _x)₂As₂ superconducting compounds, Ba (Fe _0.961 Rh_0.039)₂As₂ shows strong evidence of competition and coexistence between superconductivity and antiferromagnetic order below the superconducting transition, T_c =14 K. The transition temperatures for both the magnetic order and orthorhombic distortion are in excellent agreement with those inferred from resistivity measurements, and both order parameters manifest a distinct decrease in magnitude below T_c. These data suggest that the strong interaction between magnetism and superconductivity is a general feature of electron-doped Ba (Fe_1-x T M_x)₂ As₂ superconductors (TM=transition metal).
