Popis:	This article presents the production and structural and magnetic characterization of the Bi1-xYxFeO3 System x = 0 and 0.07, the samples were obtained by solid state reaction method. The samples were characterized by x-ray diffraction (XRD), electron microscopy scanning SEM and Mössbauer Spectroscopy. The analysis by Rietveld refinement, allowed to determine system Bi1-xYxFeO3 crystallizes in the Group R3c (161) rhombohedral. The obtained results allowed to conclude that the replacement of Bi by ions of and influence the appearance of Bi2Fe4O9 impurities, without affecting the structural response of the samples with the increase of doping yttrium.
