Abstract

Local structure of the La-based superconducting copper oxides has been studied by polarized Cu K-edge extended X-ray absorption fine structure (EXAFS) measurements. A study reveals anomalous temperature-dependent Cu–O displacements for the underdoped and optimally doped systems while no such anomaly has been found for the overdoped case. We find that the amplitude of temperature-dependent step-like increase in the correlated Debye–Waller factor of the Cu–O bonds decreases with increasing doping. The results also suggest substantial effect of substitutional disorder, shown by the large decrease in the anomalous temperature and decreased amplitude of the anomaly with increasing disorder.
