    "abstract": "We demonstrate detection of NMR signals using a non-cryogenic atomic\nmagnetometer and describe several novel applications of this technique. A water\nfree induction decay (FID) signal in a 0.5 $\\mu$T field is detected using a\nspin-exchange-relaxation-free K magnetometer and the possibility of using a\nmulti-channel magnetometer for 3-D MRI requiring only a single FID signal is\ndescribed. We also demonstrate detection of less than $10^{13}$ $^{129}$Xe\natoms whose NMR signal is enhanced by a factor of 540 due to Fermi-contact\ninteraction with K atoms. This technique allows detection of less than $10^{9}$\n$^{129}$Xe spins in a flowing system suitable for remote NMR applications.",
