| Abstract: | The authors have prepared metastable solid solutions between cubic iron sesquioxide γ-Fe2O3 and zinc ferrite ZnFe2O4. They give the main characteristics of these defect spinels. Fe3+ ions and vacancies are replaced by Zn2+ ions on tetrahedral sites. The lattice parameter and the thermal stability increase with the substitution rate. The magnetic behavior is comparable to that observed for solid solutions M1?yZnyFe2O4. |
