Abstract
Magnetic hyperfine fields at 119Sn in ferrimagnetic Fe3O4 and γ-Fe2O3 were measured by means of Mössbauer spectroscopy. The mean values at 4.2 K in Fe3O4 and γ-Fe2O3 were −241 kOe and −115 kOe respectively. The difference is explained by assuming that the transferred hyperfine contributions from A-site Fe3+, B-site Fe3+ and B-site Fe2+ are −117 kOe/atom, 113 kOe/atom and 40 kOe/atom, respectively.
