Outline of Final Research Achievements

The purpose of this research was to develop hybrid magnetic particles (ANC) for next-generation digital mobile application. The ANC were prepared by NiZn ferrite (NZF) plating on the surface of amorphous Fe-B sub-micron particles (AFBS). The following results were obtained. Dispercity of AFBS was improved using ultrasonic agitation and addition of sodium oleate. ANC showed high electric resistivity. The polymer composites using ANC did not show high permeability but they showed high electric resistivity and good microwave absorption properties comparable to existing materials.
