We report temperature and thermal-cycling dependence of surface and bulk structures of double-layered perovskite Sr3Ru2O7 single crystals. The surface and bulk structures were investigated using low-energy electron diffraction LEED and single-crystal x-ray diffraction XRD techniques, respectively. Single-crystal XRD data is in good agreement with previous reports for the bulk structure with RuO...
