quantum information processing, for which tunable dipolar coupling is required. We have linked these two spin qubit candidates together and characterized the resulting electron paramagnetic resonance properties, including the spin dipolar coupling between the fullerene spin and the copper spin. Having interpreted the distance-dependent coupling strength quantitatively and further discussed the antiferromagnetic
顺磁性内嵌
富勒烯和
酞菁 (Pc) 配合物是分子量子信息处理的有前途的构建块,为此需要可调偶极耦合。我们将这两个自旋量子位候选者联系在一起,并表征了由此产生的电子顺磁共振特性,包括
富勒烯自旋和
铜自旋之间的自旋偶极耦合。定量解释了距离相关的耦合强度并进一步讨论了 CuPc 部分的反
铁磁聚集效应,我们展示了两种调整此类二元系统中偶极耦合的方法:改变间隔基团和调整溶液浓度。
