title: Structure study on SrRu(1-x)MnxO4 using the extended X-ray absorption fine structure spectroscopy.
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 Sr2Ru(1-x)MnxO4 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.
