Fe-B-P submicron particle chains and (Ni0.6Zn 0.4)Fe2O4 nanoparticles were synthesized by chemical methods. (Ni0.6Zn0.4)Fe2O4 nanoparticles were used to fill in the space among Fe-B-P chains under a magnetic field. The synthetic composite of Fe-B-P chains filled with 20 vol.% (Ni0.6Zn0.4)Fe2O4 nanoparticles exhibits the highest intrinsic permeability(142). It is due to the enhanced performance of Fe-B-P particle chains and the effect of (Ni0.6Zn 0.4)Fe2O4 nanoparticles, which both decrease the demagnetization field. The composite film also shows a better power loss feature on coplanar transmission line than pure Fe-B-P chains, and the resonance frequencies of the composite films on coplanar line shift to about 20-30 GHz, which is caused by a large demagnetizing field due to the narrow line width of coplanar line.
