Abstract: | Ni-Co-Fe-P soft magnetic coating with amorphous structure was electroless plated onto silicon wafer substrate. The surface morphology, thickness, composition, structure and magnetic properties of coatings were observed and determined by scanning electron microscope (SEM), energy dispersive X-ray spectrometry (EDX), X-ray diffractometer (XRD) and vibrating sample magnetometer (VSM). Permeability spectra of the sample was obtained by a shorted micro strip transmission-line perturbation method. The plating with the saturation magnetization of 381 emu/cc, and the coercivity of 1.6 Oe. The film exhibits an in-plane uniaxial anisotropy of 18 Oe, and the ferromagnetic resonance frequency was as high as 760 MHz, implying that the film is promising for high frequency applications. |
