Abstract :
It has been shown that mechanical milling of iron in water results in formation of nanocrystalline magnetite Fe3O4 with an average particle size of 0.6 μm, saturation magnetization of 77 Am2/kg and coercivity of ∼150 A/cm. Along with magnetite, an antiferromagnetic Fe–O phase (∼10 wt%), which is an aggregate of small iron-oxygen clusters forms.
