Magnetic properties and structural parameters of nanosized oxide ferrimagnet powders produced by mechanochemical synthesis from salt solutions

The phase composition, the structural parameters, and the basic magnetic characteristics of a number of nanosized powders of simple spinel ferrites produced by the method of mechanochemical reactions from salt systems were studied. The influence of size and surface effects on the saturation magnetization and magnetic anisotropy was determined. The applicability of the shell model to the description of the magnetic properties of nanosized spinel ferrites is discussed.
