Аннотация

Nanodimensional spherical powders of oxide cubic ferrimagnets are obtained by mechanochemical synthesis. Their phase composition, morphology, dispersity, specific surface, and magnetic properties are determined. It is established that the synthesized ferrites are nanodimensional powders with a highly developed surface (S = 100-160 m2/g), and their magnetic characteristics substantially differ from those for bulk ferrites. As the structural element is reduced from 1000 to ~3-16 nm, ferrimagnets acquire the properties of cluster spin glass with a high blocking temperature.
