Material
Name
Co doped maghemite nanoparticles ($Fe2O3:Co_{ads}$) in sol-gel silica heated at 600°C
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; 3) heat treatment in air at 600°C for 1h. Full details in publication. The Co/Fe atomic ratio is 0.009.
