In this paper, the applications and properties of the manganese-zinc and nickel-zinc soft ferrites are presented. The requiremetnts for the recipe and the effects of additives are emphasized and reviewed with reference to the current research situation and development. Finally, the future work of soft magnetic ferrites, including prospective research aspects and properties to be reached, are proposed. The recipe is the key factor to determine the properties of the ferrites.The additive is one of the effective methods to improve the properties of the ferrites. The sintering technique is the key point to fabricate high-performance ferrites. The ferrites with properties, such as high frequency, low power waste, and high permeability, and surface mounting device will be the future trends. Also, nano magnetic ferrites need further investigation.
