Abstract

The power loss of Mn-Zn ferrites and its dependency on the microstructural factors have been investigated. The power loss was found to be lowered due to the formation of a high-electrical-resistive boundary layers, which is accomplished by an addition of specific refractory oxides, which are concentrated on the grain boundary and form a boundary layer with CaO. The new material, having a low power loss at high frequency (∼1 MHz), has been developed with the HfO2 addition.
