Thepolar Kerr effect in the spin-triplet superconductor Sr₂RuO₄ was measuredwith high precision using a Sagnac interferometer with a zero-areaSagnac loop. We observed nonzero Kerr rotations as big as65 nanorad appearing below T_c in large domains. Our resultsimply a broken time-reversal symmetry state in the superconducting stateof Sr₂RuO₄, similar to ³He-A.
