摘要：

Mechanical alloying of Mn2O3 + 2Fe(2)O(3) in air resulted in formation of a mixture of MnFeO3 and Fe2O3, while milling under an argon atmosphere resulted in the formation of the magnetite phase, MnFe2O4. The formation of MnFe2O4 was accelerated by additions of metallic Mn. A nanocrystalline spinel ferrite phase, MnFe2O4, was formed after annealing at 600-700 degrees C, and found to exhibit good soft magnetic properties.
