摘要：
随着自旋量子位和量子态检测架构需求的增加，对最近纳米磁体剪裁实验的新理解以及进一步揭示磁相互作用以原子接原子方式出现的机制的可能性具有重要意义。在这里，我们解决的自旋状态的分子三聚体，包括三个本地化的自旋时刻嵌入在金属隧道结，并显示对自旋相互作用可以通过分子三聚体的电子结构工程。我们发现，偏置和栅极电压诱导的本地化时刻或自旋受抑状态具有不同的稳定性，完全铁磁状态，这些状态之间的切换是可能的需求通过电气控制。量子相干性在分子三聚体的作用进行了讨论方面的自旋有序以及电子之间的相互作用的干扰和诱导退相的金属铅。这项工作为可用于量子工程系统的更强大的所有电控自旋架构奠定了基础，并作为探索磁有序和对称性中未解决问题的测试平台。
英文摘要：
Novel understanding of the recent nanomagnet tailoring experiments and the possibility to further unveil the mechanisms by which the magnetic interactions arise in an atom by atom fashion covers importance as the demand for spin qubit and quantum state detection architectures increases. Here, we address the spin states of a molecular trimer comprising three localized spin moments embedded in a metallic tunnel junction and show that the pair spin interactions can be engineered through the electronic structure of the molecular trimer. We show that bias and gate voltages induce either a completely ferromagnetic state of the localized moments or a spin frustrated state with different stabilities, and that switching between these states is possible on demand by electrical control. The role of quantum coherence in the molecular trimer is discussed with regards to the spin ordering as well as the interplay among electronic interference and induced dephasing by the metallic leads. This work sets foundations for more robust all electrically controlled spin architectures usable in quantum engineering systems and serves as a test bench for exploring unresolved questions in magnetic ordering and symmetry.
