Magnetic structure of RuSr $_{2}$ GdCu $_{2}$ O $_{8}$ determined by resonant x-ray diffraction

Abstract

X-ray diffraction with photon energies near the Ru L $_{2}$ -absorption edge was used to detect resonant reflections characteristic of a G-type superstructure in RuSr $_{2}$ GdCu $_{2}$ O $_{8}$ single crystals. A polarization analysis confirms that these reflections are due to magnetic order of Ru moments, and the azimuthal-angle dependence of the scattering amplitude reveals that the moments lie along a low-symmetry axis with substantial components parallel and perpendicular to the RuO $_{2}$ layers. Complemented by susceptibility data and a symmetry analysis of the magnetic structure, these results reconcile many of the apparently contradictory findings reported in the literature.
