Influence of Coating Content on the Magnetic Properties of Iron-MnZn Ferrite Soft Magnetic Composites

In this paper, iron powder with high purity is covered by a Mn-Zn ferrite layer, and the effect of amount of ferrite on the microstructure and magnetic properties are investigated. The morphology of the samples was characterized by scanning electron microscopy coupled with energy dispersive X-ray spectroscopy. It was shown that the particle surface layer contains a thin insulating layer of Mn-Zn ferrite, with high particle surface coverage. The...
