The dilute magnetic properties of SrSn1−xFexO3 (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 SrSnO3 doped with 2–8 % Fe show weak ferromagnetism although only paramagnetic doublets are observed in 57Fe Mössbauer spectra at room temperature (RT), whereas SrSnO3 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 SrSnO3−δ accompanying the oxygen deficiencies. It is further remarkable that poor crystalline 8 % Fe doped SrSnO3−δ obtained by annealing at 600 C shows relatively high saturation magnetization and low coercivity.
