Abstract

Nanosized Nd-doped strontium ferrites, SrNdxFe12-xO19, with x=0.3, were successfully prepared through a chemical coprecipitation process. The samples were characterized by TG-DSC, XRD, FT-IR. The results of TG-DSC and XRD showed that the single phase of Nd-doped strontium ferrite formed directly through the reaction of SrCO3, amorphous Fe2O3 and Nd2O3, without other intermediate phases. The crystallite size was around 35 nm.
