Magnetization produced by spin-polarized xenon-129 gas detected by using all-optical atomic magnetometer

The method to produce spin-polarized xenon-129 gas was based on the method of spin-exchange optical pumping (SEOP). The magnetizations produced by the hyperpolarized (HP) xenon-129 gas were analyzed from the perspective of theoretical and experimental research. The theoretical simulation was based on the conventional Bloch equation. The experimental research was based on measurements made by using an all-optical atomic magnetometer. The experimental results agreed with the theoretical simulated results, which proved that an all-optical atomic magnetometer had the ability to measure the magnetic field produced by xenon-129 nuclei in a low external magnetic field. Because the frequency of the nuclear spin precession could be detected precisely, the results showed that the mean measurement error of the gyromagnetic ratio was 1.1 × 10 ^-4 Hz/nT.
