Abstract :
In recent years, the endohedral metallofullerenes have drawn wide attention of scientists and given new impetus to the efforts toward the practical application in novel single molecular devices [1-2]. Especially, as single-molecule magnets, endohedral fullerenes can realize robust and chemically protected spin systems, and are promising candidates for molecular spintronics owing to their long magnetic relaxation times [3]. The research on spin dynamics of endohedral fullerenes is worthy and imperative, but still scarce. Here, we take one- and two-magnetic-center Co-doped carbon fullerenes, specifically [Co@C60]+ and Co2@C60, as examples to study their ultrafast, laser-induced, spin dynamics through ab initio calculations. The strain modulation on the spin-switching behavior is also explored.
