Abstract :
A new theoretical approach is proposed, which quantitatively describes the origin of the coercivity enhancement and the specific shape of the coercivity distribution curves of Co surface treated iron oxide pigments. Within the model the dependence of the coercivity distribution on the morphology, on the magnetic properties of the original precursor and on the surface treatment process is deduced.
