Faraday rotation has become a powerful tool in a large variety of physics applications. Most prominently, Faraday rotation can be used in precision magnetometry. Here we report measurements of gyromagnetic Faraday rotation on a dense, hyperpolarized 3He gas target. Here, theoretical calculations predict the rotations of linearly polarized light due to the magnetization of spin-1/2 particles on the scale of 10–7 radians. To maximize the signal, a 3He target designed to use with a multipass cavity is combined with a sensitive apparatus for polarimetry that can detect optical rotations on the order of 10–8 radians. Although the expected results are well above the sensitivity for the given experimental conditions, no nuclear-spin-induced rotation was observed.
