自旋是電子的一個量子自由度。自旋在物理的許多領域被廣泛研究，其在電子元件的應用更是建構下一世代電子科技的基石，因此，了解與學習如何在固態系統操控電子自旋是十分重要的，而這也是我們實驗的主要目標。
在自旋相關的物理研究中有兩個值得關注的議題，其分別為近藤效應與自旋軌道耦合。近藤效應的自旋翻轉機制源自於海森堡測不準原理以及局域性自旋和導電電子所形成的強關聯單態；自旋軌道耦合在相對論性的考量下結合了電子自旋以及運行的關係，並實現了以全電性的方式控制電子自旋。在我們的實驗中，兩個重要的物理在一維系統中首次被同時研究以及探討。
非尋常零偏壓效應是近藤效應的一個指標性特徵，單峰以及雙峰非尋常零偏壓效應均在零磁場的情況下被量測到，我們將零磁場雙峰非尋常零偏壓效應歸因於自旋軌道耦合的貢獻。再者，隨著外加磁場的變化，零磁場雙峰非尋常零偏壓效應有著雙、單、雙的演化現象，我們也因此提出一個簡單的物理圖像解釋這個磁場相關的演化。

Spin, a quantum degree of freedom of electrons, is widely studied in many field of physics and its application in electronics devices is one strong candidate for being the
cornerstone of the next-generation electronics technology. Therefore, it is essential to understand and learn to manipulate the spin dynamics in solid-state systems, both of which are the main focuses of this work.
Kondo effect[1] and spin-orbit interaction[2] are both fantastic physics that is related to spins. Kondo effect enhances the "spin-flip" process with the formation of
singlet state between the unpaired localized spins and conducting electrons. Spin-orbit interaction couples the electron's spin and its orbital motion, opening a gateway to the control of electron spin in a purely electrical manner. In our experiment, we combine the Kondo effect and spin-orbit interaction in a one-dimensional system.
Both single-peak zero bias anomaly (ZBA)[3], an hallmark of the Kondo effect, and double-peak ZBA appear at zero magnetic field. We attribute the zero-field double-peak
ZBA to the presence of spin-orbit interaction. Furthermore, an evolution from double- to single- and then back to double-peak ZBA are seen when we applied an in-plane magnetic field. Here we present a simple picture to explain this field-dependent evolution.
