    "abstract": "We describe a nuclear spin gyroscope based on an alkali-metal-noble-gas\nco-magnetometer. An optically pumped alkali-metal vapor is used to polarize the\nnoble gas atoms and detect their gyroscopic precession. Spin precession due to\nmagnetic fields as well as their gradients and transients can be cancelled in\nthis arrangement. The sensitivity is enhanced by using a high-density\nalkali-metal vapor in a spin-exchange relaxation free (SERF) regime. With a\nK-3He co-magnetometer we demonstrate rotation sensitivity of 5 10^(-7)\nrad/sec/Hz^(1/2). The rotation signal can be increased by a factor of 10 using\n21Ne due to its smaller magnetic moment and the fundamental rotation\nsensitivity limit for a 21Ne gyroscope with a 10 cm^3 measurement volume is\nabout 2 10^(-10) rad/sec/Hz^(1/2).",
