摘　　要：钆离子是元素周期表中自旋值最大的离子,其轨道角动量被完全淬灭,具有十分特殊的电子结构。本文以核磁共振造影剂以及分子自旋量子比特为例介绍了钆离子在前沿科技中的应用。The 4f orbitals of Gd^3+ ion are half-filled. This sort of unique electronic structure makes it behave the largest ground spin state and completely quenched orbital momentum over all the possible ions in the periodic table. Based on the introduction of the electronic structure of Gd^3+, this paper briefly discusses the application of Gd^3+ in the field of nuclear magnetic resonance imaging contrast agent and molecule qubit.

关 键 词：钆元素 核磁共振造影剂 分子量子比特
