Name
Co doped maghemite nanoparticles (Fe2O3:Coads) in sol-gel silica
Family
solid
Origin
laboratory
Comments
Powder obtained from a multi-step procedure involving : 1) the precipitation of magnetite nanoparticles,followed by a reflux treatment in the presence of cobalt(II) nitrate; 2) the dispersion of the colloid into sol-gel silica and drying. Full details in publication. The Co/Fe atomic ratio is 0.009.
