摘要:

內嵌金屬富勒烯（EMFs）由于其獨特的籠狀嵌套結構而受到研究者的關注，富勒烯碳籠的保護使得內嵌金屬離子或團簇顯示出與眾不同的電子結構及自旋特性，在量子信息處理、高密度信息存儲及量子調控等方面具有重要應用價值。本文主要介紹了具有電子自旋活性的內嵌金屬富勒烯的研究進展，分析了其電子結構及自旋特性。進一步討論了目前進行金屬富勒烯電子自旋調控的方法，如改變溫度、籠外修飾及構筑自組裝體等，通過研究富勒烯分子的電子自旋特性來探究分子的運動狀態，為構筑基于富勒烯的量子體系奠定基礎。

Abstract:

Endohedral metallofullerenes (EMFs) have attracted a variety of research interests due to their unique cage-like embedded structures. Profiting from the protection of the carbon cage, the internal metal ion(s) or cluster of EMFs exhibit distinctive electronic structures and spin characteristics, which shows important potential applications in quantum information processing, high-density information storage and quantum control. This review mainly introduces the research progress of spin-active EMFs and analyzes their electronic structures and spin characteristics, and then discusses three techniques to manipulate the electron spin of EMFs, such as changing the temperature, modifying the carbon cage and constructing self-assembly system. Through investigating the electron spin behaviors of EMFs, we can probe the molecular motion state, and thus make a foundation for building EMFs-based quantum systems.
