摘要：

An attempt was made to divide power loss in Mn-Zn ferrites into hysteresis loss, eddy current loss and residual loss factors experimentally. We noticed the correspondence between the temperature, Tmin at which hysteresis loss exhibits minimum valve, and secondary peak temperature of initial permeability. Analyzing the power loss and electrical resistivity measured at Tmin, it was found that the power loss can be divided into hysteresis loss, resistivity dependent loss component (eddy current loss) and resistivity independent loss component. Consequently, the residual loss was identified to be a loss component independent of resistivity.
