with x = 0.25*

The properties of the surface of Mn-doped Sr₃(Ru_1-xMn_x)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.
