    "abstract": "A magnetometric technique is demonstrated that may be suitable for precision\nmeasurements of fields ranging from the sub-microgauss level to above the Earth\nfield. It is based on resonant nonlinear magneto-optical rotation caused by\natoms contained in a vapor cell with anti-relaxation wall coating. Linearly\npolarized, frequency-modulated laser light is used for optical pumping and\nprobing. If the time-dependent optical rotation is measured at the first\nharmonic of the modulation frequency, ultra-narrow (~a few Hz) resonances are\nobserved at near-zero magnetic fields, and at fields where the Larmor frequency\ncoincides with half the light modulation frequency. Upon optimization, the\nsensitivity of the technique is expected to exceed 10^{-11} G/sqrt{Hz}.",
