Role of Sr Dopants in the Inhomogeneous Ground State of La2-xSrxCuO4
Abstract
Our experiments in La2-xSrxCuO4 provide evidence for a spatial correlation between the doped holes and the Sr dopants, in addition to the presence of a large hole-lattice coupling only in the vicinity of the Sr dopants. The local structure deviates from the macroscopic, average, structure at x≥0.15, indicating the appearance of structural disorder. This disorder is in the form of nanodomains, within which the local tilts are ordered, but tilts become disordered relative to each other in going from one domain to the other. These results indicate that Sr dopants might have a much more significant role in determining normal and superconducting properties of La2-xSrxCuO4 than is typically assumed
