Temperature-dependent polarized Cu K-edge x-ray absorption has been used to investigate local structural distortions in the CuO 2 plane of the La 1.85 Sr 0.15 CuO 4 system. The Cu-O pair distribution shows the presence of a minority phase containing CuO 6 octahedra characterized by a shorter Cu-O͑apical͒ bond ͑⌬RϳϪ0.1 Å͒ and two longer Cu-O͑planar͒ bonds ͑⌬Rϳϩ0.08 Å͒ and a tilting angle of 16°Ϯ2°. The temperature-dependent distortions show a maximum around T* (ϳ1.6T c ) and a minimum at T cdoi:10.1103/physrevb.55.12759 fatcat:agr3x5gijnglvmemlpih4peh4i
