Abstract

We report the magnetic ordering and structural distortion in PrFeAsO crystals, the basis compound for one of the oxypnictide superconductors, using high-resolution x-ray diffraction, neutron diffraction, and x-ray resonant magnetic scattering (XRMS). We found the structural tetragonal-to-orthorhombic phase transition at TS = 147 K, the AFM phase transition of the Fe moments at TFe = 72 K, and the Pr AFM phase transition at TPr = 21 K. Combined high-resolution neutron diffraction and XRMS show unambiguously that the Pr moments point parallel to the longer orthorhombic a axis and order antiferromagnetically along the a axis but ferromagnetically along the b and c directions in the stripe-like AFM order. The temperature dependent magnetic order parameter of the Pr moments shows no evidence for a reorientation of moments.
