Abstract：

A　circular　molecule　named　{Fe8Dy8}　with　fixed　toroidal　magnetic　moment　below　a　certain　temperature　can　be　used　for　high-density　information　storage.　The　energy　gap　between　this　toroidal　ground　state　(blue　molecule)　and　the　first　excited　state　(reddish　molecule)　causes　the　S-shaped　magnetization　plot　at　low　field,　while　such　a　toroidal　moment　is　caused　by　the　ferromagnetic　exchange　interaction　between　the　metal　centers.　The　strong　magnetic　anisotropy　of　the　dysprosium(III)　ions　determines　the　toroidal　directions　(arrows　in　the　molecular　wheel).　©　2020　Elsevier　Inc.
