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

摘要

The synthesis of transparent and magnetic iron oxide/Vycor-glass (VG) composites was discussed. The glass composite was prepared by impregnation of slices of porous VG rods with an iron nitrate solution followed by a thermal treatment and a reduction process. Transmission electron microscopy (TEM) was used to observe the narrow particle size distribution. It was found that the composites exhibited Faraday rotation.
