In this paper, the hollow sphere Fe3O4 powders pepared by the solvothermal method were mixed with Co nanoparticles (prepared by arc-discharge, the size about 100nm), the quality ratio of Fe3O4 and Co is 4:1. The SEM study shows that the Fe3O4 powders have Hollow sphere structural with the size of about 200nm. As a result, when Co nanoparticles are introduced, Fe3O4/Co composite absorbent is obtained enhanced microwave absorption properties, which is attributed to the improved synergistic effect of dielectric and magnetic components between εr and μr. The results show that Fe3O4/Co composite absorbent is great potential microwave absorbents for practical applications.
