论文摘要
我们调查了在非常低的温度下，介质铂纳米结构（电线和环）的磁转移特性。尽管铂的旋转轨道相互作用很强，但发现电导的振荡与量子干扰效应引起的外部磁场的关系。由于磁通量刺穿环和形成纳米结构的金属电线，振荡分解为AHARONOV-BOHM周期性振荡和电导的静脉波动。我们还研究了不同偏置电流下的磁转移，以探索强旋转轨道导体中电子相一致性和自旋积累效应之间的相互作用。
We investigated the magnetotransport properties of mesoscopic platinum nanostructures (wires and rings) with sub-100 nm lateral dimensions at very low temperatures. Despite the strong spin-orbit interaction in platinum, oscillations of the conductance as a function of the external magnetic field due to quantum interference effects was found to appear. The oscillation was decomposed into Aharonov-Bohm periodic oscillations and aperiodic fluctuations of the conductance due to a magnetic flux piercing the loop of the ring and the metal wires forming the nanostructures, respectively. We also investigated the magnetotransport under different bias currents to explore the interplay between electron phase coherence and spin accumulation effects in strong spin-orbit conductors.
