Crystal structure and cation distribution of nanocrystalline SrFe 1-xTixO3-δ (0 ≤ x ≤ 0.3) synthesized by combined high-energy ball milling and solid-state reactions are investigated using Neutron powder diffraction and Mössbauer spectroscopy. Ti doping stabilizes the single phase tetragonal structure with I4/mmm space group up to x = 0.3. The neutron and Mössbauer data confirm that Fe exists in three different sites both crystallographically as well as magnetically in all the four compositions. The cation distribution at various sites is established through Rietveld refinement. © 2013 The American Ceramic Society. Source
