Abstract :
Fe microparticle composites with different nanoparticles were prepared using Ni-Zn ferrite and Fe-B-P amorphous nanoparticles. Both additions into iron microparticles significantly increase magnetic permeability, whereas Fe-FeBP composite exhibits more advantages than Fe-(Ni0.6Zn0.4)Fe2O4 composite due to higher saturation magnetization (Ms). The magnetic field range with high permeability is about 0-600 Oe for Fe-FeBP composite, whereas it decreases to 0-80 Oe for Fe-(Ni0.6Zn0.4)Fe2O4 composite. The permeability of Fe-FeBP composite remains high up to about 1 GHz and the resonance frequency is about 2 GHz, which is higher than that of Fe-(Ni0.6Zn0.4)Fe2O4 composite.
