YBa2(Cu1-xFex)3O7-y thick films (x=0, 0.01, 0.02, 0.03) on ceramic substrate were prepared. X-ray diffraction determinations show the formation of partial c-axis texture perpendicular to the surface of the ceramic substrate in the preparation process. The57Fe Mössbauer spectra were measured at 300 K, where the angle θ between the incidence γ-ray beam and the surface of the film is 90° and 36°, respectively. The57Fe Mössbauer spectra with θ=90° possess four sets of asymmetrical doublets.
