Complex Permeability of Ferrites Correlated with their Microstructure
The totality of spinel and garnet polycrystalline ferrite (PF) samples is divided in two subgroups in process of their complex initial permeability (including the static value) relating to their microstructure (MS). The analysis for the first, including PF of rather perfect MS brings to explicit relations showing the effects of grain size distribution. For the other, the group of typical PF, the observed effects is possible to evaluate basing on the results gained for the first group.
