我们演示了使用非低温原子磁强计检测核磁共振信号，并描述了该技术的几个新应用。利用无自旋交换弛豫的钾磁强计探测到来自水的核自旋进动信号。我们还发现了少于10(13)Xe-129的原子，它们的核磁共振信号由于与K原子的费米接触作用而增强了540倍。文中还讨论了利用多道原子磁强计进行快速三维磁共振成像的可能性。
We demonstrate detection of NMR signals using a noncryogenic atomic magnetometer and describe several novel applications of this technique. A nuclear spin-precession signal from water is detected using a spin-exchange-relaxation-free potassium magnetometer. We also demonstrate detection of less than 10(13) Xe-129 atoms whose NMR signal is enhanced by a factor of 540 due to Fermi-contact interaction with K atoms. The possibility of using a multichannel atomic magnetometer for fast 3D magnetic resonance imaging is also discussed.
