我们演示了一种横向极化自旋交换泵浦惰性气体磁强计，它抑制了纵向极化引起的系统误差。Rb原子以及$^{131}$ Xe和$^{129}$ Xe原子核垂直于脉冲偏置场同时极化。通过脉冲重复频率的调制，可以同时满足两种氙同位素的核磁共振条件。Rb原子探测到Xe进动。我们强调磁强计相移在进行磁强计时的重要性。对于非磁自旋相关相互作用的检测，传感带宽为1 Hz，白噪声电平为7 $\mu$ Hz / $\sqrt{\text{Hz}}$，偏置稳定性为$\approx1$$\mu$ Hz。
We demonstrate a transversely polarized spin-exchange pumped noble gas comagnetometer which suppresses systematic errors from longitudinal polarization. Rb atoms as well as $^{131}$Xe and $^{129}$Xe nuclei are simultaneously polarized perpendicular to a pulsed bias field. Both Xe isotopes' nuclear magnetic resonance conditions are simultaneously satisfied by frequency modulation of the pulse repetition rate. The Rb atoms detect the Xe precession. We highlight the importance of magnetometer phase shifts when performing comagnetometry. For detection of non-magnetic spin-dependent interactions the sensing bandwidth is 1 Hz, the white-noise level is 7 $\mu$Hz /$\sqrt{\text{Hz}}$, and the bias stability is $\approx1$ $\mu$Hz.
