Effective permeability of nanoscale particle of W-type hexaferrite

In the paper there has been conducted the calculation of effective permeability of a nanoscale particle of W-type hexaferrite by alteration of added Zn ions from 0.8 to 2. It has been shown, that increasing of permeability of solid material leads to increasing of a surface portion into the main volume of the particle. The results that have been obtained by us justify the necessary correction of the relationship theory of composite mixtures when manufacturing the composite materials based on nanoscale powders.
