A high coercivity of up to 5.1 kOe was induced in a large-grained CoFe2O4 powder after milling for a short time (1.5 h). It was found that the initial grain (particle) size played an important role in the microstructural evolution and in the magnetic properties of the milled CoFe2O4 materials. The m...
