| Abstract: | Zn0.23Mn0.70Fe2.07O4 power ferrite material was prepared by solid-state reaction method.Magnetic properties and power losses of the material were investigated by MATS,and SY-8232 B-H.The hysteresis loss,eddy current loss and residual loss were separated from the total power loss of MnZn ferrites at 100kHz,200mT.The results showed that the II peak appeared at 80℃,corresponding to the temperature of minimal hysteresis loss.The loss characteristics of materials were affected significantly by temperature.At normal temperature,the hysteresis loss account most of the total loss of material,but the eddy current losses gradually become the main part of material loss with increasing temperature. |
