High-frequency electromagnetic properties of soft magnetic Y2Fe17Nx particles with easy-plane anisotropy

The microwave magnetic properties of the soft magnetic Y2Fe17Nx (x≈3) particles with easy-plane anisotropy were reported. The high MS and out-of-plane anisotropy result in the high permeability in GHz frequency band. The complex permeability of the Y2Fe17Nx particles/paraffin composite was further enhanced by inducing the easy magnetization planes of the particles to be parallel to each other through a rotational orientation. The calculated reflection loss (RL) properties of the orientated Y2Fe17Nx composite revealed that this composite can be used as high-performance absorber in S band.
