MnZn ferrite is one of important magnetic materials. The materials have been interested and widely studied because of its special property since 1930s. The property of MnZn ferrite are closely relative to composites and structure of the materials. The methods of process of MnZn ferrite have an significant effect on the property too. In this paper, the background, significance and current state of manufacturing high permeability MnZn ferrite was summed up and at the same time the investigation status about composition, sintering process and methods of analysis was reviewed. We can make further research on MnZn ferrite by studying the trends of MnZn ferrite.
