Abstract： A series of samples Bal+xNdl-xFeTiO6(x = 0.0-0.5) were prepared by solid state reactions and characterized by x-ray diffraction and Mössbauer spectroscopy. All samples crystallized in cubic structure. A random distribution of Fe and Ti ions at octahedral sites was shown. 57Fe Mössbauer spectra of the samples consisted of a quadrupole doublet. The quadrupole splittings obtained by fitting the experimental data were larger than 0.5mm/s, indicating local structure distortions in these cubic phases. The relationship between quadrupole splitting and dopant content x of Bal+xNdl-xFeTiO6is discussed.
