Abstract: Nanocrystalline Ni-Zn ferrite was synthesized by mechanochemical reaction from α-Fe2O3,ZnO and NiO powders through high energy ball milling. The synthesized samples were characterized by XRD, TEM and Mossbauer spectroscopy. The results showed that the as-millednanocrystalline size was about 5~20 um, which exhibited superparamagnetism, and the size ofthe nanocrystallite after annealed at 800℃ for 2h increased to about 50 um, which exhibitedferrimagnetism

Key words: mechanochemical synthesis, nanocrystalline, Ni-Zn ferrite
