Реферат:
57Fe Mössbauer spectroscopy data obtained between 4.2 and 298 K, TEM, and magnetic measurements were used to study details of the real structure of cobalt oxides, CoO and Co3O4. In Co3O4 samples synthesized at low temperatures the tracer is nonuniformly distributed. It exists in the form of α-Fe2O3 inclusions generating stacking faults as well as in the form of Fe3+ ions in octahedral positions of the spinel matrix. An excess of oxygen in Co3O4 was found to generate cation vacancies in the octahedra. The two-phase CoO-Co3O4 system displays a dislocation network broadening the resonance lines and increasing the quadrupole splitting. For monophasic CoO an excess of oxygen leads to the formation of microclusters of Co3O4. A periodic array of shear type extended defects found in modified CoO was proposed to be generated by ordering of Fe impurities in some planes of the cubic structure.
