The paramagnetic metallofullerenes wrapped lanthanide metals have many special properties and potential applications, especially as a single-molecule magnet. Herein, we report a spin probe of nitroxide radical for the magnetic dysprosium metallofullerenes. The nitroxide radical was connected to dysprosium metallofullerene though a cycloaddition reaction. Two kinds of dysprosium metallofullerene, DySc₂N@C₈₀ and Dy₂ScN@C₈₀ with different characters of molecule magnet, were selected. By means of analyzing electronic spin resonance spectra of nitroxide radical, the spin-paramagnet interactions between nitroxide and dysprosium metallofullerenes were investigated.
