This work proposes an easy and scalable convergent synthesis method to obtain heterodimers formed by multi-walled carbon nanotubes and magnetic nanoparticles via carbon-nitrogen bonds. Magnetic nanoparticles were synthesized by solvothermal method. Heterodimers were characterized by X-ray diffraction, Fourier Transform Infrared Spectroscopy, Transmission Electronic Microscopy and magnetic properties. The magnetic nanoparticles have a mixed crystal structure, mostly formed by maghemite and a small fraction of hematite. Infrared Spectroscopy and Transmission Electronic Microscopy confirm the formation of heterodimer magnetic nanoparticles ? carbon nanotubes via covalent bonds. Magnetic measurement indicates that it is possible to adjust the magnetic response according to the final application.
