Magnetic Properties Dependence of Polymer Nanocomposite on Iron Oxide nanoparticles Concentration

To study the nature of anisotropy effects in samples of polymer (PVA) films containing nanoparticles of magnetite, depth selective conversion Mossbauer spectroscopy (for layer‐by‐layer phase and magnetic analysis), natural remanent magnetization Jn measurements in three mutual — orthogonal directions and atomic force microscopy were used. These investigations revealed formation of the “in plane” direction of linear Fe3O4 nanoparticles chains and their number increases with nanoparticles concentration growth in the samples.
