    "abstract": "We propose a new method of spin squeezing of atomic spin, based on the\ninteractions between atoms and off-resonant light which are known as\nparamagnetic Faraday rotation and fictitious magnetic field of light. Since the\nprojection process, squeezed light, or special interactions among the atoms are\nnot required in this method, it can be widely applied to many systems. The\nattainable range of the squeezing parameter is S^{-2/5}, where S is the total\nspin, which is limited by additional fluctuations imposed by coherent light and\nthe spherical nature of the spin distribution.",
