The composites have been studied by Mössbauer spectroscopy, XRD, TEM and SQUID. Correspondence between the hyperfine parameters and the iron oxide particle size and magnetic behaviour has been proved. The prepared composites differ in magnetic properties, size and morphology of the iron oxide particles.
