We have modifed a fiber-optic gyroscope based on the Sagnac interferometer to measure nonreciprocal phase shifts. The instrument has a sensitivity of better than 1 μrad and is insensitive to any reciprocal phase shifts. Thin films of high-temperature superconductors (HTSC) have been measured in search for nonreciprocal effects below Tc due to "Anyon superconductivity'' ground state. No nonreciprocal phase shift was observed in any of the measured samples.1 The Faraday effect in various magnetic thin films (e.g., EuO) have been measured using the instrument showing a great sensitivity to submonolayers of the materials.〈ks〉
