| Abstract: | The γ-Fe2O3 magnetic powder samples with Co-doping prepared by different technological process and some other magnetic powder products were studied by means of M?ssbauer effect of 57Fe, magnetism measurements and chemical analysis. The experimental results indicate that the changes of coercivity are related to microstructure, this is shown in the M?ssbauer spectra.
