In this letter, the surface of carbon nanoutubes was successfully decorated by Fe3O4 via a simple and effective coprecipitation and hydrothermal treatment method. Then the resultant composite were characterized. The results showed that Fe3O4 nanoparticles in the surface of carbon nanotubes were uniform and universal; The composite was ferromagnetic and also had better absorbing properties in the 0-5GHz range. CNTs/Fe3O4 composite had significant potential for electromagnetic wave absorption application in tumor hyperthermia.
