Abstract

The intrinsic spin of the electron and its associated magnetic moment can provide insights into spintronics. However, the interaction is extremely weak, as is the case with the coupling between an electron’s spin and a magnetic field, and it poses significant experimental challenges. Here we demonstrate the direct measurement of polarized single NV^– centers and their spin–spin coupling behaviors in diamond. By using photoinduced magnetic force microscopy, we obtain the extremely weak magnetic force coupling originating from the electron spin. The polarized spin state of NV^– centers, transitioning from |0⟩ to |±1⟩, and their corresponding Zeeman effect can be characterized through their interaction with a magnetic tip. The result presents an advancement in achieving electron spin measurements by magnetic force, avoiding the need for manufacturing conductive substrates. This facilitates a better understanding and control of electron spin to novel electronic states for future quantum technologies.

利用光诱导磁力显微镜直接检测电子自旋的磁力和磁场耦合

电子的固有自旋及其相关磁矩可以让我们深入了解自旋电子学。然而，这种相互作用极其微弱，就像电子自旋与磁场之间的耦合一样，给实验带来了巨大挑战。在这里，我们展示了在金刚石中直接测量极化单个 NV 中心及其自旋-自旋耦合行为的方法。通过使用光诱导磁力显微镜，我们获得了源自电子自旋的极弱磁力耦合。NV- 中心的极化自旋状态（从|0⟩过渡到|±1⟩）及其相应的泽曼效应可以通过它们与磁尖的相互作用来表征。该成果在通过磁力实现电子自旋测量方面取得了进步，避免了制造导电基底的需要。这有助于更好地理解和控制电子自旋，为未来的量子技术提供新的电子状态。
