| Abstract: | We report an experimental study of the crystallographic lattice, morphologic characteristics and magnetic feature of Sr2RuHoO6 complex perovskite, which is used as a precursor in the fabrication process of the superconducting ruthenocuprate RuSr2HoCu2O8. 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) Å, b=5.8784(5) Å, c=8.1651(9) Å, and tilt angle β=90.200°. Magnetic susceptibility measurements reveal the occurrence of an antiferromagnetic ordering for a Néel temperature TN=10.1 K. From the Curie-Weiss fitting of the paramagnetic regime we obtain an effective magnetic moment of 11.31 μB. |
