Structural and Mossbauer Investigation of Nanocrystalline SrFe1-xTixO3-delta
Crystal structure and cation distribution of nanocrystalline SrFe1-xTixO3- (0x0.3) synthesized by combined high-energy ball milling and solid-state reactions are investigated using Neutron powder diffraction and Mossbauer spectroscopy. Ti doping stabilizes the single phase tetragonal structure with I4/mmm space group up to x=0.3. The neutron and Mossbauer 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.
