抄録

It is exemplified that a novel approach for controlling the electromagnetic properties and microstructure has given excellent results in the development of new Mn-Zn ferrites.<BR>The investigation about the effects of nanostructural improvement on the electromagnetic properties was performed by introducing a new method of power loss analysis, which is characterized by plotting the power loss versus reciprocal of electrical resistivity at the secondary peak temperature of the permeability. An eddy current loss obtained by this analysis is two times larger than the calculated one. The residual loss was identified as a loss factor which is not related to the resistivity and closely associated with frequency as well as applied magnetic field.<BR>Sintering conditions influences the distribution of additives in the microstructure, which is responsible for the loss factors.
