SrSn1-x-yFexSbyO3-δ was prepared by a sol-gel and thermal annealing method. The lattice parameters of SrSn0.97-xFexSb0.03O3-δ (x = 0.04-0.15) decreased with the increase of Fe doping rates. All samples showed ferromagnetic behavior together with a paramagnetic component, relatively strong ferromagnetism for SrSn0.97-xFexSb0.03O3-δ and SrSn1-xFexO3-δ with Fe doping rates over 6% and 8%, respectively The Sb doping leads to the ferromagnetic behavior for the samples with the low-concentration of Fe dopant. 119Sn Mössbauer spectra of SrSn0.92Fe0.08O3-δ and SrSn0.88Fe0.12O3-δ provided a broad doublet under a magnetic field of 0.85 T. The doublet could be analyzed as a magnetic sextet with 0.76 T. In 57Fe Mössbauer spectra of SrSn0.88Fe0.12O3-δ under zero and 0.85 T different line intensity ratios of two sextets were observed. It suggests that the magnetic spin structure of SrSn1-xFexO3-δ is transversely ferrimagnetic.
