Mn- and Co-BiFeO 3 polycrystalline films were prepared by a chemical solution deposition (CSD) method and their structures were investigated by grazing incidence X-ray diffraction (GIXRD) and θ-2θ XRD in conjunction with transmission electron microscopy (TEM). GIXRD measurement revealed that the Mn-BiFeO 3 film contains the Bi 2Fe 4O 9 pyrochlore phase, which might be attributed to the low magnetization of the Mn-BiFeO 3 film. For the Co-BiFeO 3 film, secondary phases were not observed by structural analyses and the composition was almost homogeneous. From the analytic aspect of the structure, the magnetization enhancement in the Co-BiFeO 3 films is considered to be associated with Co substitution for Fe in BiFeO 3.
