Closed-Loop Control of Compensation Point in the K−Rb−21Ne Comagnetometer

“…In all of these applications, the long-term stability of the comagnetometer is essential and often limited by noise and systematic effects associated with the external magnetic fields and magnetization due to spin dipolar interactions [14,15]. In general, comagnetometers with two or more nuclear species calculate an appropriate combination of nuclear precession frequencies to cancel out magnetic field dependence [16][17][18]. Based on dual nuclear isotopes differential technique, a three-axis residual magnetic fields closed-loop control system has been incorporated in NMR gyros to guarantee the long-term stability of magnetic fields [19][20][21].…”
