Vector magnetometry using perfectly aligned nitrogen-vacancy center ensemble in diamond

We demonstrate vector magnetometry using ensemble of the nitrogen-vacancy (NV) centers in diamond that are perfectly aligned along the [111] direction. By changing the direction and strength of the reference magnetic field, we perform three-dimensional vector measurement of the Oersted field generat...

Description
Summary:We demonstrate vector magnetometry using ensemble of the nitrogen-vacancy (NV) centers in diamond that are perfectly aligned along the [111] direction. By changing the direction and strength of the reference magnetic field, we perform three-dimensional vector measurement of the Oersted field generated by the current flowing in a nearby wire. We had a formula for evaluating the magnetic field sensitivity in the direction perpendicular to the NV axis. We demonstrate that the expected sensitivity is 1.2 times higher than that of the NV ensemble isotropically oriented on four equivalent crystal axes. Our precise method is suitable for time-varying magnetic signals.
