摘要：
The activation volume and the crystallite size in gamma-Fe2O3 and Co-modified gamma-Fe2O3 particles have been determined. For fixed particle volume the variation tendencies of the activation volume and crystallite size are the same. It seems to be that the crystallite size influences the activation volume in these materials.
