Highly transparent γ-Fe2O3/Vycor-glass magnetic nanocomposites exhibiting faraday rotation

The preparation and characterization of highly transparent (see Figure) and magnetic nanocomposites exhibiting Faraday rotation is reported. Superparamagnetic behavior results from the confinement of the gamma-Fe2O3 nanoparticles within the pores of a Vycor glass. The remarkable Faraday rotation exhibited by the resulting composites opens their application to a wide range of magneto-optical devices.
