论文摘要
传感小磁场与从地质到医学诊断的许多应用相关。我们提出了一个光纤耦合的钻石磁力计，其灵敏度为（310 $ \ pm $ 20）pt $/\ sqrt {\ text {hz}} $在10-150 Hz的频率范围内。这是基于室温下钻石中氮气空位中心的光学检测到的磁共振。纤维耦合意味着可以方便地将传感器带入正在研究的物体的2 mm之内。
Sensing small magnetic fields is relevant for many applications ranging from geology to medical diagnosis. We present a fiber-coupled diamond magnetometer with a sensitivity of (310 $\pm$ 20) pT$/\sqrt{\text{Hz}}$ in the frequency range of 10-150 Hz. This is based on optically detected magnetic resonance of an ensemble of nitrogen vacancy centers in diamond at room temperature. Fiber coupling means the sensor can be conveniently brought within 2 mm of the object under study.
