Temperature Dependence of the Surface Structure of Sr<sub>3</sub>(Ru<sub>1-x</sub>Mn<sub>x</sub>)<sub>2</sub>O<sub>7</sub> with x = 0.25

ORAL

Abstract

The properties of the surface of Mn-doped Sr3(Ru1-xMnx)2O7 are fundamentally different from the bulk: The surface is conducting (insulating) while the bulk is insulating (conducting). Furthermore, the surface has enhanced rotation and tilt that is removed by x = 0.16 Mn doping. Further studies show a surface structural transition that is driven by the bulk magnetic ordering. Here we report the surface properties of the x = 0.25 sample, where both structural distortion and magnetic ordering no longer exist in bulk. Low Energy Electron Diffraction show that the surface remains as a reconstructed structure due to the octahedral rotation. The temperature dependence of the electronic and structural properties will be discussed and compared to recent theoretical calculations for the ground state.
