Optically pumped quantum magnetometer employing two components of magnetic moment precession signal

The new scheme of a combined quantum magnetometric device is proposed that represents a fast M X magnetometer, in which the phase of M X signal detection is corrected with respect to the maximum of the variable component of the atomic magnetic moment. The device combines a high response speed (τ ≤ 0.1 s) with high precision, which is determined by the resolving power of the quantum M X magnetometer for a time of an order of 100 s. The reproducibility of field measurements is on a level of 2–3 pT.
