N2 - Manganese ferrites, MnFe 2O 4±δ, synthesized via mechanosynthesis from different manganese sources, MnO, Mn 2O 3 and MnO 2, and mixed with Fe 2O 3, were studied. XRD, SEM and magnetometry were used to characterize the synthesized powders. The MnFe 2O 4 spinel phase appeared after 12 h of milling when MnO and MnO 2 mixed with Fe 2O 3 were used as the precursors and showed the maximum saturation magnetization value (49.77 emu/g). Manganese ferrite did not form when MnO 2 was used. Manganese ferrite obtained from Mn 2O 3 showed the lowest saturation magnetization value. An increase in the milling time promoted the increase in the saturation magnetization values.
