论文摘要
我们在这里描述了高分辨率光学磁力计的构建和表征，以测量设备表面附近的超薄层上的全矢量磁场。该固态设备基于由一层由氮气散发（NV）中心产生的量子传感器，该中心低于超音钻石表面以下20 nm。这种纳米传感器的合奏提供了一种多功能装置，能够以亚微米分辨率和高灵敏度绘制磁场和表面电流密度，从而适合许多应用。在这里，我们展示了一个定制的原型，以演示操作概念验证设备。
We describe here the construction and characterization of a high-resolution optical magnetometer to measure the full vector magnetic field on an ultrathin layer near the surface of the device. This solid-state device is based on quantum sensors created by a layer of nitrogen-vacancy (NV) centers less than 20 nm below the surface of an ultrapure diamond. This ensemble of nanosensors provides a versatile device capable of mapping magnetic fields and surface current densities with a sub-micrometer resolution and high sensitivity, making it suitable for many applications. Here, we show a custom-built prototype to demonstrate an operating proof-of-concept device.
