Abstract

The developed technology provides obtaining finely-dispersed ferrite powders ZnxFe3-x04 (x=0-0.5), which meet the requirements to magnetic na noagents used in the biomedical field such as biochemical purity, n a n ometric particle size, rather high magnetization and superparamagnetic state in the therapeutic range of temperatures. T h e average particle sizes have been determined by the methods of X-ray d iffraction analysis and e l e ctron microscopy. T he dependence of the crystalline lattice constants on the zinc ions concentration has been determined. Magnetic measurements at 300 K have demonstrated the increase of magnetization as a result of replacement of iron ions with zinc ions and the size effect - the superparamagnetic state of the powder particles has been found.
