The low-temperature magnetic properties of the endohedral metallofullerene HoSc2 N@C80 have been studied by superconducting quantum interference device (SQUID) magnetometry. Alternating current (ac) susceptibility measurements reveal that this molecule exhibits slow relaxation of magnetization in a small applied field with timescales in the order of milliseconds. The equilibrium magnetic properties of HoSc2 N@C80 indicate strong magnetic anisotropy. The large differences in magnetization relaxation times between the present compound and the previously investigated DySc2 N@C80 are discussed.
通过超导量子干涉装置（SQUID）磁力测定法研究了内嵌金属富勒烯HoSc₂N@C₈₀的低温磁性。交流（ac）磁化率测量表明，该分子在小外加磁场中表现出磁化强度的缓慢弛豫，时间尺度约为毫秒量级。HoSc₂N@C₈₀的平衡磁性表明其具有很强的磁各向异性。讨论了本化合物与先前研究的DySc₂N@C₈₀之间磁化弛豫时间的巨大差异。
