Abstract
The local structure around the Cu atoms in rare earth (RE) doped (La,S r)(2)CuO4 has been studied by means of measuring the X-ray absorption fine structure (XAFS) at the Cu K-edge. On the local scale the tilting angle of the oxygen octahedra a surrounding a Cu atom depends on the Sr and RE content. No anomalies indicating charge modulation in this s ystem have been found.
