The shape of the surface isotherms and the electron-micrograph pictures appear to be strongly dependent on the particle size. Small particles are organized in more compact aggregates than larger ones. We interpret this behavior as a size-dependent balance between van der Waals and magnetic interparticle interactions. 关键词: ;
