Abstract
Rare earth soft magnetic alloys have potential in high frequency applications due to strong easy-plane anisotropy. As the research progressed, a new resonance peak in the MHz frequency band, the domain wall resonance peak was observed, which seriously affects applications of magnetic materials in power device. A way to decrease it is by increasing domain wall resonance frequency (fdw). In this paper, the composites of easy-plane Y2Fe17 and polyurethane were presented and the easy-plane Y2Fe17 were treated by nitriding and doping. It is found that both nitriding and doping are effective in increasing the permeability. And the frequency of domain wall resonance peaks is varied due to the variation in exchange interaction by nitriding and doping. These results provide insight into soft magnetic properties of soft magnetic composites (SMCs) in the MHz frequency band, particularly for SMCs in power devices applications.
