We have investigated a molecular relaxation process in a solid polymer filled with dispersed magnetite particles (Fe3O4 in epoxy resin). In particular, we compare systems containing nano-particles…
On the dielectric and magnetic properties of nanocomposites

- 2007
Materials Science, Physics
We investigate nanocomposites, that is, dispersions of magnetite nanoparticles in an epoxy resin, by means of broadband dielectric and magnetic spectroscopy. The molecular dynamics of the polymer…
