Fe 3 O 4 nanoparticles dispersed on single‐walled carbon nanotube (SWCNT) composites are synthesized through a simple in‐situ co‐arc discharge process followed by an annealing process. A well‐integrated Fe 3 O 4 /SWCNT composite exhibiting the strong microwave absorption (MA, −36.9 dB at 10.5 GHz) and a wide effective bandwidth (5.5 GHz) is obtained by controlling the annealing conditions. The high effective MA performance of this composite was ascribed to the well integration of magnetic nanoparticles (Fe 3 O 4 ) on the SWCNT, creating a synergetic effect. This work demonstrates an economical approach to produce Fe 3 O 4 /SWCNT composites with good MA performance.
