Frequency dispersion model of the complex permeability of soft ferrites in the microwave frequency range

Antonio Barba-Juan et al.

Summary: A mathematical model has been proposed in this study to fit the measured magnetic permeability spectra of Cu-doped nickel-zinc polycrystalline ferrites, with a range of average grain sizes and relative densities. For the first time, domain-wall motion and spin rotation contributions to magnetic permeability have been integrated with microstructure in the model, highlighting their relative influences at different angular frequencies.

Phase Formation, Microstructure and Permeability of Fe-Deficient Ni-Cu-Zn Ferrites, (I): Effect of Sintering Temperature

Christoph Priese et al.

Summary: The study investigates the effect of stoichiometry and Fe-deficiency on the properties of Ni-Cu-Zn ferrites, and observes phase formation, microstructure changes, and permeability variations under different sintering temperatures and compositions.
