Abstract
Section titled āAbstractāWe demonstrate a three-axis vector magnetometer based on ensembles of negatively charged nitrogen vacancy centers in single-crystal diamond. A diamond with C3v symmetry 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 of ~ 5 nT āHz for each Cartesian component, free of interaxis error. The magnetometer is suitable for single-chip manufacturing.
