Comparison between DySc 2 N@C 80 and Dy 2 ScN@C 80 single-molecule magnetic metallofullerenes encapsulated in single-wall carbon nanotubes.

Encapsulation of a metallofullerene single-molecule magnet, Dy 2 ScN@C 80 , into single-wall carbon nanotubes (SWCNTs) accelerates magnetic relaxation processes. In contrast, encapsulation of DySc 2 N@C 80 suppresses them. The effects of the encapsulation are discussed in terms of intermolecular magnetic interactions and charge transfer among metallofullerenes and SWCNTs.
