Description
Fe-doped nanosized SnO2 powders were prepared by mechanosynthesis using rutile SnO2 and hematite Fe2O3 as starting materials. The estimated grain size of the obtained rutile structure was between 10 and 20 nm. Moessbauer spectroscopy shows the presence of two interactions corresponding to 3+ and 2+ iron oxidation states with similar relative fractions. The magnetic measurements exhibit ferromagnetic- (FML) and superparamagnetic-like (SML) behavior. Evidence of a system of strongly interacting particles was found
