摘要：

Microstructures, electronic structures, and microwave absorption properties of Fe3Si/PPy composites have been investigated through experiments and first principal method. The calculated results show that Fe3Si/PPy composites are ferromagnets, and the total magnetic moment is 1.87(mu B). Charge transfer between atoms is conducive to dielectric loss. The Fe3Si/PPy composites were prepared with the one-pot method. The presence of Fe3Si and PPy was confirmed by XRD, FTIR, EDS and TEM. The Fe3Si/PPy composites showed good wave-absorbing ability in the X-band and Ku-band in contrast to pure Fe3Si. T...
