Samples of anti-electromagnetic interference(EMI) Mn-Zn ferrite were prepared by solid-phase sintering method, and the disaccomodation of initial permeability was studied. The results indicate that the disaccomodation factor increases as a result of increase of Fe2+ content in the spinel crystal lattice, and higher Curie temperature results in higher disaccomodation factor DF. The disaccomodation coefficient d of anti-EMI Mn-Zn ferrite is dependent on its initial permeability.
