Mechanochemical synthesis and magnetic properties of maghemite

Vojnotehnički Glasnik, 2011
This work presents the results of an investigation on maghemite (γ -Fe2O3) nanoparticles magnetic properties, which show superparamagnetic behavior i.e. superparamagnetism. Nanoscale maghemite samples were obtained by the mechanochemical method.
