标题： Two molecular devices for superconducting spintronics

摘要： 我们使用二茂镍分子、单个铁原子和铅电极在低温下创建了两个超导结分子器件。 我们发现铁原子的配位导致了不同的行为：一个器件由于多个安德烈夫反射（MAR）和铁诱导的间隙内态的叠加，在微分电导中表现出低偏压特征。 另一个器件则展示了MAR与间隙内态之间的干涉，展示了在具有相同组分的原子工程器件中可实现的多样性。 显示英文摘要

摘要： We create two molecular devices with superconducting junctions, using nickelocene molecules, single Fe atoms, and Pb electrodes at low temperature. We find contrasting behavior based on the coordination of the Fe atom: one device shows low-bias features in its differential conductance due to the superposition of multiple Andreev reflections (MAR) and Fe-induced in-gap states. The other reveals interference between MAR and in-gap states, showcasing the diversity achievable in atomically engineered devices with identical components.
