(a) Structure of inside of magnetometer head: excitation coil, cancellation coil, MW coil, diamond NV, and optical fiber. (b) Calculated magnetic field of excitation (red) and cancellation (blue) coils on Z-axis. The black line indicates the summation of the excitation and cancellation magnetic fields. (c) Enlarged figure for only resultant magnetic fields.
