Description:
Ferromagnetic (FM) spin fluctuations are believed to mediate the spin-triplet pairing for the p-wave superconductivity in Sr(2)RuO(4). Our experiments show that, at the surface, a bulk soft-phonon mode freezes into a static lattice distortion associated with an in-plane rotation of the RuO(6) octahedron. First-principle calculations confirm this structure and predict a FM ground state at the surface. This coupling between structure and magnetism in the environment of broken symmetry at the surface allows a reconsideration of the coupling mechanism in the bulk.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matzdorf -- Fang -- Ismail -- Zhang -- Kimura -- Tokura -- Terakura -- Plummer -- New York, N.Y. -- Science. 2000 Aug 4;289(5480):746-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physics and Astronomy, The University of Tennessee, Knoxville, TN 37996-1200, and Oak Ridge National Laboratory (ORNL), Oak Ridge, TN 37831-6057, USA.
