Abstract
Highly steady composites of FeCo alloy and carbon nanotubes have been synthesized by in situ catalytic decomposition of benzene over FeCo alloy nanoparticles generated through procedures of sol-gel fabrication and hydrogen reduction. Magnetic measurement indicates that the coercivity (HC) increases with the rise of Co concentration and the saturation magnetization (MS) rises in the order of FeCo13@C<FeCo31@C<FeCo22@C. The complex permittivity and permeability of the composites indicates that the maximum reflection loss (RL) is -6.7 dB at 11.1 GHz at thickness of 1.5 mm for FeCo13@C, and as well as the electromagnetic wave absorption properties can be tuned by adjusting the composition of FeCo alloy and the absorption layer thickness.
