Abstract
The evolution of the hard and soft modes in the crystal structure of MnxZny FezO4 manganese-zinc spinel ferrites is investigated theoretically and expe rimentally (x-ray structure analysis and magnetic measurements). It is show n that tetragonal and rhombohedral distortions of the cubic structure and f luctuations of the soft mode are accompanied by the formation of clusters i n the form of quasi-two-dimensional fragments (50-200 and 400-1200 Angstrom ), which involve families of gamma -Mn2O3, gamma -Mn3O4, and alpha -Fe2O3 o xide planes inherently bound to the spinel matrix.
