Tin-doped spinel has been reported as a classical soft magnetic material. In this study, series spinels of Fe3-xSnxO4 were synthesized via a novel low-temperature solid-state reaction process from natural magnetite and cassiterite. The substitution mechanisms between Sn4+ and Fe3+ were investigated by means of XRD, TEM, XPS, M?ssbauer, FT-IR analysis, etc. The results indicated that the maximum doping stoichiometric content of tin was 0.5 in Fe3-xSnxO4. The substitution occurred prior to proceeding in the octahedral void between Sn4+ and Fe3+, because the ion radius of Sn4+ is very similar to Fe3+ and much smaller than Fe2+. In addition, the effects of tin content on the magnetic properties were revealed. The optimal coercivity value of 10.2 Oe was obtained for Fe2.9Sn0.1O4, which can be used as soft magnetic material. This is related to the lattice distortion caused by Sn4+.
