Abstract

SrSn_1-x-yFe_xSb_yO_3-δ was prepared by a sol-gel and thermal annealing method. The lattice parameters of SrSn_0.97-xFe_xSb_0.03O_3-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 SrSn_0.97-xFe_xSb_0.03O_3-δ and SrSn_1-xFe_xO_3-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 SrSn_0.92Fe_0.08O_3-δ and SrSn_0.88Fe_0.12O_3-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 SrSn_0.88Fe_0.12O_3-δ under zero and 0.85 T different line intensity ratios of two sextets were observed. It suggests that the magnetic spin structure of SrSn_1-xFe_xO_3-δ is transversely ferrimagnetic.
