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 -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.
