| Abstract: | The existence of fast electron exchange between pairs of Fe3+?Fe2+ ions was detected in Mössbauer spectra of non-stoichiometric CoNiZn ferrites containing an excess of Fe2O3. Analysis of spectra from a number of samples of various preparations showed correlation of bulk magnetic properties with hyperfine parameters of ferric ions at octahedral sites in the spinel structure. |
