摘要：
Single nanocrystalline spinel phases have been formed in mechanically alloyed CoFe2O4 and Co0.8Fe2.2O4 powders after heat treatment at temperatures above 750 degrees C. High coercivities (2.6-2.7kOe) were associated with nanocrystalline structures in CoFe2O4. In Co0.8Fe2.2O4 a high remanence equal to 78% of the saturation magnetisation and a coercivity of 3.2kOe were obtained in magnetically annealed samples.
