The dilute magnetic properties of SrSn
1?xFe
xO
3 (x = 0.01 ? 0.15) prepared by sol-gel and thermal decomposition methods were investigated by
57Fe Mössbauer spectrometry, magnetometry, and X-ray diffractometry. It was found that SrSnO
3 doped with 2–8 % Fe show weak ferromagnetism although only paramagnetic doublets are observed in
57Fe Mössbauer spectra at room temperature (RT), whereas SrSnO
3 doped with 10–15 % Fe show relatively strong ferromagnetism, and the sextets are additionally observed in the
57Fe Mössbauer spectra at RT. The weak ferromagnetism by doping 2–8 % Fe is considered to be caused by the induced magnetic defects, and the ferromagnetism by doping 10–15 % Fe are considered mainly due to the magnetic coupling between dilute Fe
3+ partially substituted at Sn
4+ sites in the orthorhombic structure of SrSnO
3?δ accompanying the oxygen deficiencies. It is further remarkable that poor crystalline 8 % Fe doped SrSnO
3?δ obtained by annealing at 600
°C shows relatively high saturation magnetization and low coercivity.
