Abstract: The octahedron (BO6) plays a crucial role in ground state for the layered perovskites oxides. Here, we report a structure study of the octahedra in Sr2Ru1-xMnxO4 based on Extended X-ray Absorption Fine Structure (EXAFS) method. EXAFS results reveal a clearly structural distortion around the doped Mn atoms, and Jahn-Teller effect in MnO6 octahedra could be expected in the octahedra. This structural distortion may related to the chemical valance change when doping.

Keywords: EXAFS, layered peroviskite oxides, structure distortion
