摘要
A series of samples Ba_(1+x)Nd_(1-x)FeTiO_(6)(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.^(57)Fe 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 Ba_(1+x)Nd_(1-x)FeTiO_(6) is discussed.
