摘要

In this work, the microwave electromagnetic performances of ferrocenyl organic magnetic material as being influenced by a rare earth metallic oxide Eu₂O₃ doping have been investigated. The dopant concentration was varied between 1 and 4 wt.%. The results obtained revealed that the electromagnetic parameters including complex permittivity and permeability at high frequencies changes with the vibration of the dopant concentration of Eu₂O₃. Furthermore, the microwave absorbing capacity at high frequencies was increased by increasing the dopant concentration of Eu₂O₃. The maximum microwave absorption of 鈭?#xA0;15.8 dB at Ku-band, which was much bigger than that of pure ferrocenyl organic magnetic material, achieved from the doping concentration of 4%for Eu₂O₃.
