Ferrite samples of composition Cu0.12Ni0.23Zn0.65(Fe2O4) have been prepared by a conventional ceramic process using different sintering temperatures and dwell times. The average particle size is around 25–30 nm and, after sintering, the average grain size increases to 0.2–5 μm and the relative density is between 88 and 95 % of the theoretical density.
This paper shows that the mathematical model previously tested on ferrite microparticles with the same composition, is also capable to fit the measured complex magnetic permeability-imaginary part u11 and to explain why this magnetic property decreases when the particle size of the starting powder changes from micro to nano size. The model confirms the dependence of the magnetizing mechanisms (spin rotation and domain-wall motion) on the two microstructural parameters: average grain size (G) and relative density o/ of the sintered body.
