摘要：

The atomic dynamics of ultrafine clusters of gamma-ferric oxide with diameters of 1-3 nm, obtained by thermal decomposition of ferric oxalate, has been studied by gamma-resonance (Mossbauer) spectroscopy and by thermodynamic analysis. The intracluster atomic mobility has been shown to increase by the action of surfactants. Thermodynamical and phenomenological cluster models describing the dynamic state of clusters have been developed and are compared with the experimental data. The conditions for formation of a specific solid-liquid state of clusters are discussed.
