分子纳米磁体的研究进展及应用

Progress of Researches and Applications on Molecular Nanomagnets

分子磁学主要研究无机配合物以及有机自由基的电子结构和磁性之间的关系。近些年发展起来的分子纳米磁体可以在单分子尺度上实现磁双稳态,独立作为一个磁功能单元,可能突破尺寸对传统磁性材料的制约,有望实现超高密度磁存储。分子纳米磁体中清晰的量子态也为量子退相干研究提供了化学调控的手段,这将为量子计算机提供物质基础。本文简要介绍了分子纳米磁体的概念和特征,并对研究进展进行了简要综述。

Molecular magnetism researches the electronic structures of inorganic coordination complexesand organic radicals and their effects on the magnetic properties. The recent developments of molecularnanomagnets reveal that the magnetic bistablity can be achieved in an individual molecule, which isconsidered as a potential candidate for data storage materials of ultrahigh density. The well-definedquantum states of molecular nanomagnets also offer the chemical tuning access in the quantumdecoherence investigation, laying the material foundation of quantum computer. In this paper, we brieflyintroduce the idea and properties of molecular nanomagnets, and the related researches are reviewed.
