| Popis: | We report an experimental study of the crystallographic lattice, morphologic characteristics and magnetic feature of Sr 2 RuHoO 6 complex perovskite, which is used as a precursor in the fabrication process of the superconducting ruthenocuprate RuSr 2 HoCu 2 O 8 . The samples were produced through the standard solid state reaction. A Rietveld refinement of experimental X-ray diffraction patterns shows that the material crystallizes in a monoclinic structure, which belongs to the P21/ n (#14) space group, with lattice parameters a= 5.7719(6) A, b =5.8784(5) A , c =8.1651(9) A, and tilt angle β =90.200°. Magnetic susceptibility measurements reveal the occurrence of an antiferromagnetic ordering for a Neel temperature T N =10.1 K . From the Curie-Weiss fitting of the paramagnetic regime we obtain an effective magnetic moment of 11.31 μ B . |
