Summary

The paper describes the magnetic behavior of polymer-nanocomposites containing nanoparticles (∼10 nm) of maghemite γ-Fe203 and magnetite Fe304 in a polyvinyl alcohol matrix. The compositions were synthesized using an original method of the in situ preparation, the reaction of oxide formation taking place inside the polymer matrix itself. It is the one-domain-per-particle nature of magnetism in the given polymer nanocomposites that was found to be responsible for such a distinctive feature as superparamagnetism detected using Mössbauer spectroscopy and magnetization measurements. The giant negative magnetoresistance was found in the highly filled compositions. As far as we know this is the first time when this effect is observed in polymer composites based on ferrite nanoparticles.
