Controlled fabrication of materials by surface modification techniques has been a hot research topic.In this paper,one-dimensional(1D)core-shell structure Fe@Co nanowires(NWs)were successfully prepared by anchoring 0-dimensional(0D)Co nanoparticles on 1D Fe NWs based on the in situ reduction method.The electromagnetic parameters of the specimens at a filler mass fraction of 25 wt%were tested and the microwave loss mechanism was deeply analyzed.Binary magnetic metals in a core-shell structure have excellent multi-band microwave absorption capability(S-band,X-band and Ku-band).This is due to the heterogeneous interface and magnetic coupling effects tuning the dielectric and magnetic loss.This study offers a workable plan for creating effective multi-band magnetic metal-based microwave absorbers.
