Abstract

Encapsulation of a metallofullerene single-molecule magnet, Dy₂ScN@C₈₀, into single-wall carbon nanotubes (SWCNTs) accelerates magnetic relaxation processes. In contrast, encapsulation of DySc₂N@C₈₀ suppresses them. The effects of the encapsulation are discussed in terms of intermolecular magnetic interactions and charge transfer among metallofullerenes and SWCNTs.
