Abstract

The magnetic properties of hematite (α-Fe2O3) nanoparticles synthesized by in situ thermal decomposition of an iron-mercaptide precursor in polymeric matrices are studied. In Polystyrene, nanoparticles with average size ∼20 nm can be produced that show ferromagnetic behavior with no Morin transition for temperatures as low as 10 K. Poly (9-vinylcarbazole)- based nanocomposites, produced by the same synthesis process, show a different magnetic behavior with a clear Morin transition. The effect of the polymeric matrix on the structural and magnetic properties of dispersed hematite nanoparticles is discussed. It is concluded that, in heavily viscous medium, the ability to control the particle growth and distribution is compromised. © Springer Science+Business Media Dordrecht 2012.
