Title: High Resolution Polar Kerr Effect Measurements of Sr2RuO4: Evidence for Broken Time Reversal Symmetry in the Superconducting State

Abstract

Polar Kerr effect in the spin-triplet superconductor Sr{sub 2}RuO{sub 4} was measured with high precision using a Sagnac interferometer with a zero-area Sagnac loop. We observed non-zero Kerr rotations as big as 65 nanorad appearing below T{sub c} in large domains. Our results imply a broken time reversal symmetry state in the superconducting state of Sr{sub 2}RuO{sub 4}, similar to {sup 3}He-A.
