| Abstract: | The chemical states of119Sb5+ ions hydrolytically adsorbed on spinel type ferrimagnetic oxide CoFe2O4 powders are studied by means of emission Mössbauer spectroscopy of the daughter nuclide119Sn. The spectra show a broadening which is attributed to the supertransferred hyperfine magnetic field coming from the magnetically ordered metal ions of the substrate. Distribution of the field is obtained from the spectra and its change with temperature is discussed. |
