A series of Fe 3− x Mn x O 4 samples with x=0–0.6 was prepared using the hydrothermal method. The system was characterized using transmission Mössbauer spectroscopy. The dependence of the site hyperfine magnetic fields and populations on the content x of Mn substitution was derived from the spectra. The results are consistent with Mn 2+ ions substituting for Fe 2+ ions in the octahedral B sublattice. In particular, the site-specific substitution of Mn ions for the B2 sites was evidenced.
