Binding for endohedral-metallofullerene superatoms induced by magnetic coupling

Abstract

To design new materials based on artificial superatoms, clarifying their involved interaction is particularly important. In this study, we discuss first-principle calculations to show that the interaction between endohedral metallofullerenes (EMFs) of U@C₂₈ can lead to different chemical and physical adsorption structures. Especially, these structures are derived from different magnetic coupling resonances, and they can transform by changing the distance between U@C₂₈ superatoms. These findings will promote the future development for bottom-up assembling of new functional materials and even devices.
