我们展示了一种基于单晶金刚石中带负电荷的氮空位中心系综的三轴矢量磁强计。利用具有对称性的钻石建立了矢量磁场传感的坐标系。我们用三轴亥姆霍兹线圈来控制外部静磁场。得到了四对磁共振峰，用于计算磁场的三个笛卡尔分量，每个笛卡尔分量的灵敏度为f，没有轴间误差。该磁强计适用于单片制造。
We demonstrate a three-axis vector magnetometer based on ensembles of negatively charged nitrogen vacancy centers in single-crystal diamond. A diamond withsymmetry was used to establish the coordinate system for vector magnetic field sensing. We control the external static magnetic field with three-axis Helmholtz coils. Four pairs of magnetic resonance peaks were obtained, which were used to calculate the three Cartesian components of the magnetic field with sensitivity offor each Cartesian component, free of interaxis error. The magnetometer is suitable for single-chip manufacturing.
