The complex permeability of the Cu-doped Ni–Zn polycrystalline ferrites is strongly dependent on microstructure, particularly on relative density (ϕ) and average grain size (G), as it has been shown in a previous study
developed at a constant angular frequency (107 Hz). In this study, the previous microstructural model proposed
has been extended to an angular frequency range (from 106 to 109 Hz) demonstrating its validity and reliability.
In addition, domain-wall motion and spin rotation contributions to magnetic permeability have been individually
considered in the mathematical model, highlighting the relative influence of each magnetizing mechanism at
different angular frequencies. [-]
