摘要：
The magnetic behavior of polymer nanocomposites containing nanoparticles (similar to10 nm) of oxidized magnetite in a polyvinyl alcohol matrix were investigated by means of Mossbauer transmission and conversion electron spectroscopy and magnetic measurements. The obtained results show that the base concentration of iron oxide nanoparticles within the polymer matrix volume greatly influences the magnetic properties of nanocomposites. The estimated lamellar distribution of superparamagnetic Fe3O4 islands actuates the magnetic anisotropy formation in the investigated films. (C) 2002 Elsevier Science B.V. All rights reserved.
