• Using a phenomenological two-fluid model we derive the Kerr rotation of the polarization direction of reflected light from the surface of a superconductor in a state breaking time-reversal symmetry. We argue that this effect found recently in the superconducting state of $Sr_2RuO_4$ by Xia et al (Phys.Rev.Lett. {\bf 97}, 167002 (2006)) originates from the spontaneous magnetization in this superconductor. The temperature and the frequency dependencies of the effect are established. It is shown… CONTINUE READING
