Effect of the content of dopants in the manganese-zinc ferrites on the low power loss is studied by measuring magnetic properties and observing the grain boundary structures. The Mn_0.738Zn_0.206Fe_2.056O_4 composition powders were prepared by using conventional ceramic powder processing technique. The microstructure of grain boundary was observed by scanning electron microscope (SEM). It has been found that power loss is greatly dependent upon the content of the additives.
